Edible souvenirs to buy in Britain for yourself or for friends and family who weren't lucky enough to go with you.
I'm a big fan of buying food items as gifts, for other people in particular as they can absolutely represent the country you have visited and while they may be available back home, the chances are you'll have to search for them, have a very limited choice if you do find them, they'll be more expensive and possibly taste rather differently as they aren't made the same way. They are also generally unlikely to be something tried by most people.
There's a good opportunity to personalize the gift according to the tastes of the recipient too and it is less likely to be simply discarded as an odd reminder of somewhere someone else went to once.
Gift shops v supermarkets and other grocers:
There are many food gifts in gift-shops often wrapped and presented more nicely than the ordinary food from everyday grocery shops. However.... I recommend that you don't get it from the gift shops and instead go to a grocery shop or supermarket to buy food gifts because the quality of the food will be better and it will also be cheaper and fresher, I'm always suspicious when I see wrapped gift shop foods with very long sell by dates much longer than normal, what do they put in it to make it last?
I suggest you find a Waitrose supermarket or Marks and Spencer food hall nearby these are generally reckoned to be upmarket but still affordable food shops and there are many branches across the country. Many of their foods will cost less than those sold in gift shops and will be better quality too.
Small "whole foods" stores are good places to buy locally produced foods.
There are some food gift shops I can recommend, these are the ones you will find at National Trust or English (and Scottish) Heritage properties if you visit them. They generally have a range of nicely labeled and packaged produce from the local area if not from that actual property itself if it has a farm or working estate attached.
Chocolates and sweets (candy):
British chocolate is unlike European or American chocolate. You can get it anywhere, it's not too expensive and is a great gift for a chocolate fan. If you haven't tried it before, there are variety packs of smaller bars to get a taste of the options. While you can get British chocolate brands in other countries, it often tastes different (and not as good) as it does in the UK.
Maltesers: milk chocolate covered
Dairy milk: traditional British milk chocolate bars.
Aero: chocolate bars with air bubbles, totally changes the texture, try the mint.
Flake: a stick made of very thin rippled chocolate, stuck in an ice-cream it makes it a "99" but no-one knows why.
Roses: selections of chocolates with different flavoured centres.
Heroes: Individually wrapped bite size min-bars of the most popular Cadbury chocolate bars.
Celebrations: As with Heroes, but made by Mars.
There are dozens of different types of sweets from traditional and quirky to more familiar international brands. if you want more then seek out a traditional "Sweet Shop", most small towns and upwards in size will have one.
My favourites are wine gums, midget gems, and sports mixture, traditional chewy, fruit flavoured, fairly hard gummy sweets.
I've never found proper British style tea outside of Britain (and Ireland), there is some stuff made by Liptons which you can find most places, but it's always disappointing and you never see it for sale here. There are endless little gift shop tins with a union flag on them or shaped like a phone box, Big Ben, a Harrods van or similar that have tea in them which are quite nice in themselves, but as for the tea? no thanks. British style tea is of course not actually grown in Britain but imported, largely from Kenya, Uganda, Assam in India and Sri Lanka.
If you want to get some tea to take home that is actually drunk and enjoyed in Britain, then I recommend Yorkshire tea, PG Tips or slightly more upmarket offerings from Twinings, "everyday", "breakfast" or my particular favourite, Darjeeling. If you want to deliver it in one of those tins, get an empty tin and fill it with tea from the supermarket. Most tea is now bought as bags, loose leaf is available may be a little more difficult to seek out if you want a particular type.
Duchy of Cornwall originals:
A company set up by Prince Charles, the Prince of Wales in 1990 to sell organic food products. It is now a brand that supplies a whole range of traditional British organic foods. Many of these are fresh produce such as meat and vegetables, but there are also things such as biscuits, honey, chutney and jam which make good gifts, partly because of their royal connection and partly because they are often attractively packaged in a way that you expect of a gift. They cost somewhat more than the equivalent "ordinary" brand, but usually less than you would pay for a similar thing in a "gift shop".
You can find this range in the supermarket chain Waitrose which has over 350 shops across the UK.

A kind of jam made from citrus fruits and containing thin slivers of softened peel, though peel-less versions are also available. Most commonly, Spanish Seville oranges are used to make marmalade. It has a sweet/tart flavour with the pieces of peel giving extra texture, it is usually eaten at breakfast on toast so you'll almost certainly be able to sample it during your stay here as it will probably be provided on the table. There are many different varieties, though the basic Seville orange is the most popular, I like it with plenty of pieces of peel and I'm quite a fan of lemon marmalade too. Marmalade with whisky is frequently seen and considered a luxury version, though tends not to be too popular, I think the whisky flavour detracts rather than adds to it.
Crisps, (you may know them as potato chips) are big business in the UK and are available in what those from other countries apparently consider to be strange and exotic flavours, this always comes as news to the British who consider them perfectly normal.
Some flavours are always available, others are trials for short periods or may just be seasonal especially for Christmas. A large supermarket nearby has these flavours currently for sale amongst others: Cheese and onion, flame grilled steak, prawn cocktail, sour cream and black pepper, bbq beef, smoky bacon, roast chicken, marmite, mango and chili chutney, Peking spare rib, wasabi and ginger, pulled pork, jerk chicken, goats cheese, red pepper, lime and coriander, Worcester sauce, chorizo and onion, ham and cranberry, tomato ketchup and more... Pickled onion Monster Munch also deserves a honourable mention here.
They make a cheap, tasty and interesting gift, while they are somewhat bulky, they are lightweight. Put them in a shoe box in your luggage, or a plastic container or even small cardboard box from the supermarket.
Britain produces over 700 different types of cheese of a whole range of different types but is most famous for cheddar which originated in the Somerset village of the same name in about the 12th century if not earlier. So if you want to take some cheese home go for cheddar. Avoid the cheaper industrially produced cheese, you want some aged or vintage cheddar from a smaller produced to get the best, these are at the stronger or sharper end of the taste scale, cheese counters will often let you have a small piece to try. The other British specialty which is famous here but much less well known overseas is stilton, this is a crumbly blue cheese with a strong flavour, it is akin to other blue cheeses though has it's own unique character. If you are a fan of blue cheeses, make sure you try it.
Not British cheese - if you are visiting from outside Europe and are taking cheese home I strongly suggest you take some European ones too which are readily found here. My own favourites that I have taken as gifts and have gone down well include French Brie-de-Meaux (brie of designated origin) and Italian Taleggio, if you are a fan of very strong cheese, then some French Époisses de Bourgogne is a must.
To transport cheese put it in a plastic sealable container and keep the cheese in it in the fridge until the last possible moment, then wrap in the middle of your luggage surrounded by clothes for insulation and unpack it as soon as you can. You may also find cheese in decorative ceramic pots, stilton may be found like this, it's much more expensive as you're paying for the pot too, but makes a nice gift.
A great favourite is butter shortbread, made with butter (I bet you guessed that), cheaper shortcake is made with vegetable fat. There are a number of different shapes, petticoat tails which are circular with marked segments, scotty dogs, stars, other animal shapes, Christmas shapes etc. The cheapest in terms of weight per unit cost are the simple fingers which are made to the same recipe and taste exactly the same but are a bit less special to receive.
Other British biscuits. The thing you need to understand about biscuits in Britain is that almost without exception, they were designed to accompany a cup of tea. So while they may seem a bit dry and hard in isolation, all is revealed when washed down with a cup of tea. Dunking biscuits in tea is widely practised, very short dunk times of about one second are recommended for beginners and debate rages over whether it is acceptable to dunk chocolate covered biscuits or not (though clearly it is not). The repeat Olympic champion of dunkable biscuits is the "Rich Tea" as it demonstrates the greatest resilience and is least likely to end in disaster - half a biscuit falling off into your tea.
As gifts, unless you have a particular favourite, there are tins and boxes of assorted biscuits at different price points and levels of poshness.
Chutney's and pickles:
Fruit and/or vegetables mixed with sugar and vinegar as preservatives and to make a thick sauce may be additionally flavoured with spices. Pickles have less sugar and often more oil, they are a different product altogether to simply pickled vegetables such as gherkins, onions and cucumber. Chutney's and pickles are a result of the influence of Indian cookery on British food using largely ingredients that grow here. They are eaten in particular with cheese and cold meats, Indian style chutney's and pickles may be used to accompany hot foods too. An important component of a ploughman's lunch.
There are endless varieties available, a few from you may encounter: red onion, tomato, plum, rhubarb, apricot and ginger, green tomato and many more, a mainstream mass produced best seller is Branston Pickle, but beyond this any supermarket, National Trust gift shop, cheese shop, delicatessen etc. will have a range of chutney's and pickles in all kinds of flavours and combinations. You could go to the same places and get Indian style such as mango chutney (usually quite a mild flavour, though can be spicy), mango pickle, brinjal (aubergine) pickle or lime pickle (usually strongly flavoured and very spicy). Piccalilli is a relish with fairly chunky vegetables made yellow with mustard.
Local honey can be bought all over the UK and so can be a good local food linked to specific area to buy as a souvenir. Supermarkets always have honey and may also have local produce, though you are more likely to find it in small wholefood shops or markets. If you have a hire car and are driving along country roads in the summer look out for small roadside stalls that are selling honey (they may also have other things such as eggs and vegetables) with a honesty box for payment.
There are many bottled beers widely available in Britain including selection packs of 4-6 different types from one particular brewery. If you're flying, then weight becomes an issue along with potential breakages. Recently there are more "real ales" and beers from micro-breweries available in cans which are lighter than bottles and less likely to break, though are not quite as attractive a gift as bottles. Supermarkets generally have a good selection or look for an "off licence" nearby, a shop that sells alcohol to be consumed off the premises - as opposed to on the premises as with a pub.
