What’s the Difference Between Jam and Marmalade?

People use “jam” and “marmalade” almost interchangeably, yet in the UK the two words mean genuinely different things, and the law backs that up. The short version? Marmalade can only be made from citrus fruit. Jam can be made from almost any fruit you like. That single rule sits behind every other difference, from the bittersweet bite of a good Seville orange marmalade to the soft, fruity set of a strawberry jam. We make both by hand here in the Cotswolds, so we live with these distinctions every day. Below, we’ll explain exactly what separates them, what the rules say, and how to choose the right one for your toast.

What is the difference between jam and marmalade?

The core difference is the fruit: marmalade is made from citrus and contains peel, while jam is made from non-citrus fruit such as berries, stone fruit or currants. Under the Jam and Similar Products (England) Regulations 2003, marmalade must contain at least 200g of citrus fruit per kilo of finished product (Business Companion, 2026). Jam has its own fruit and sugar standards. Here’s a quick side-by-side.

	Jam	Marmalade
Main fruit	Berries, stone fruit, currants: almost anything except citrus	Citrus fruit only (orange, lemon, lime, grapefruit)
Peel	No peel	Defined by its peel and pith
Texture	Soft set, fruit pulp	Gel with strips of peel suspended in it
Flavour	Sweet, fruity	Sweet with a signature bitter edge
Legal status	Reserved description	Reserved description, citrus only

What exactly is jam?

Jam is a set spread made by cooking crushed or chopped fruit with sugar until it gels. To be sold as “jam” in England, a product traditionally needs a total sugar content of around 60%, alongside a minimum amount of fruit that varies by type (legislation.gov.uk, 2003). That sugar isn’t only for sweetness: it’s what gives jam its long shelf life and that glossy, spoonable set.

The fruit floor matters too. Most jams need roughly 350g of fruit per kilo, though tart fruits like blackcurrants are allowed less because their flavour is so intense. Because “jam” is a reserved description, a producer can’t simply slap the word on a low-fruit, low-sugar spread; if a recipe doesn’t meet the standard, it has to be called something else, such as a “fruit spread”.

According to Trading Standards guidance, jam is a “reserved description” that can only be used when a product meets the compositional rules in the 2003 Regulations (Business Companion, 2026). In practice, that protects you as a shopper: the word “jam” on a label is a promise about fruit and set, not just marketing.

If a classic fruity set is what you’re after, you can browse our handmade sweet preserves, jams and curds, from strawberry to damson, all cooked in small batches.

What makes marmalade marmalade?

Citrus, and citrus alone. Marmalade is a gelled mixture of sugar, water and citrus fruit, and UK rules require at least 200g of citrus per kilo, of which at least 75g must come from the endocarp, the juicy segments inside the fruit (Hampshire County Council Trading Standards, 2026). No other fruit qualifies. You simply cannot make a legal “strawberry marmalade”.

That bittersweet character everyone associates with marmalade comes from the peel and pith. Cooked slowly, the peel softens and releases bitter oils that balance the sugar, which is exactly why a proper marmalade tastes grown-up rather than simply sweet. Historically the word meant Seville orange, prized for its sharp, aromatic skin, though today you’ll find lemon, lime, grapefruit and blood orange versions too.

You can taste the difference peel makes in our Seville orange marmalade, or explore the full range of zesty handmade marmalades, from tangy lime to bittersweet grapefruit.

Is marmalade just a type of jam?

Not in Britain. Here, “jam” and “marmalade” are separate reserved descriptions, so a jar can’t legally be both (Business Companion, 2026). That’s a quirk of English, though. In French, Italian, German and Spanish, the local word for “marmalade” simply means any fruit cooked with sugar. In Seville itself, “mermelada de naranja” just means orange jam.

This linguistic split even reaches the rule-makers. In 2024 the EU introduced the term “citrus marmalade” to avoid confusion across member states. The UK government has confirmed that British marmalade isn’t changing and jars on UK shelves stay exactly as they are (UK Parliament, Hansard, 2026). So if you’re shopping at home, the simple rule still holds: citrus means marmalade, everything else means jam.

How do jam and marmalade taste, and when should you use each?

Jam leans sweet and mellow, so it suits soft bakes and creamy partners: think Victoria sponge, scones with clotted cream, or a spoonful swirled through porridge. Marmalade brings acidity and bitterness, which is why it shines on hot buttered toast, glazes for ham and duck, and even a splash in a salad dressing. Want a rule of thumb? Reach for jam when you want comfort, and marmalade when you want a lift.

Both keep beautifully thanks to their sugar content, and both make generous gifts. A bittersweet marmalade tends to win over people who claim not to have a sweet tooth, while a vivid berry jam is hard for anyone to resist.

The bottom line

The difference between jam and marmalade really does come down to one word: citrus. Marmalade is the citrus-and-peel member of the family, defined by law and by its bittersweet bite. Jam is the broad church of everything else, berries, stone fruit and currants, set with sugar into a soft, fruity spread. Once you know the rule, every jar in the shop suddenly makes sense.

Frequently asked questions

Is marmalade always made from oranges?

No. Marmalade must be made from citrus, but that includes lemon, lime, grapefruit and blood orange as well as the classic Seville orange. UK rules simply require at least 200g of citrus fruit per kilo. The citrus is the only fixed rule; the variety is up to the maker.

Why is marmalade bitter and jam isn’t?

Marmalade’s bitterness comes from citrus peel and pith, which release aromatic, slightly bitter oils as they cook. Jam uses the flesh and pulp of non-citrus fruit, so it tastes sweet and fruity instead. The peel is what gives marmalade its grown-up, bittersweet edge.

Can you make marmalade from strawberries or other non-citrus fruit?

Not legally, in the UK. Marmalade is a reserved description for citrus fruit only, so a strawberry spread can be called jam, preserve or conserve, but never marmalade. The word marmalade is protected specifically to signal citrus.

Is jam or marmalade healthier?

Both are high in sugar, with traditional recipes around 60%, so neither is a health food and both are best enjoyed in moderation. Marmalade does contain citrus peel, which carries some fibre, but the difference is small. Treat both as a delicious treat rather than a virtue.

What’s the difference between jam, jelly and marmalade?

Jam is made from crushed non-citrus fruit; jelly is made from strained fruit juice only, so it’s clear with no pieces; and marmalade is made from citrus fruit and includes peel. All three are reserved descriptions with their own legal standards in England.
