What is the secret to good marmalade? ›

Reducing the sugar in the recipe means a slacker, not set consistency and the marmalade could have a shorter shelf life. The trend normalising “soft set” as acceptable is a misleading way of saying the marmalade is set. The correct consistency is gelled, similar to a that of a jelly preserve.

After about 5 mins the marmalade will start to rise up the pan (it may drop back and then rise again) and larger bubbles will cover the surface. After 8-10 mins boiling, test for setting point. Times will vary according to the size of the pan – in a large pan this takes 7-8 mins, in other pans it may take 12-15 mins.

Granulated is the go-to sugar for marmalade making. Its larger crystals will dissolve quickly and cleanly, making a clear, amber liquid that best displays your perfectly suspended peel. White granulated and the unrefined golden granulated taste quite different to each other, and it's worth experimenting.

Pam Corbin, preserving expert and former owner of Thursday Cottage, marmalade and jam makers: After adding sugar to the oranges, stir the mixture over a gentle heat to ensure it's completely dissolved before it starts to boil. Once it's reached a rolling boil, disturb it as little as possible.

Stir in the appropriate amount of Certo, and boil as fast as possible for about 5 minutes. Test a small sample on a cold plate (put the plate in the freezer for 10 minutes). A skin should form and start to set. If still not setting, boil again for another 3 minutes and test again.

Lemons contain a very high amount of pectin, which naturally sets and thickens the marmalade.

What's the ratio of sugar to fruit in marmalade? Because of the tartness of a Seville orange, the ratio of sugar to fruit in marmalade is 2:1. This recipe calls for 2kg of sugar and 1kg of oranges but you can scale it down or up using that ratio.

To prevent scum forming on the top of your jam, add a knob of butter to your fruit at the same time as you add the sugar, we recommend 20 grams per 1 kilogram of fruit. Note: Scum is nothing sinister, it is only air bubbles that are created during the cooking process, they will not ruin your jam/marmalade if they form.

Oranges contain so much natural pectin that the marmalade will thicken without any added pectin (unlike with my peach, strawberry or raspberry jam, that all require pectin).

Why add lemon juice to marmalade? ›

Adding acid in the form of fresh lemon or lime juice is important for two reasons: First, it makes for a more well-balanced jam, returning some of the acidity lost with the addition of sugar. Second, pectin needs acid to properly activate, or firm up.

You simply spoon a little of the peel and cooking liquid onto a frozen plate, then return it to the freezer for 2 minutes. Take the plate out and push your finger through the liquid part. If it “wrinkles” and looks like, well, set jelly, you know the marmalade is ready.

If you cook it for too long at a high temperature, the natural pectin breaks down and no longer acts as a setting agent and the sugar polymerises into toffee. The way to make any set jam or marmalade is to simmer the fruit gently until it develops your desired level of softness.

Tie the muslin square into a little bag and add it to the bowl. Make sure everything is immersed in the water. Leave to soak overnight or for several hours if possible. This helps to extract pectin from the fruit and soften the peel, which will reduce the amount of cooking.

Use Valencia oranges if you can find them – if not, regular navel oranges are fine too. The main secret in producing a sweet (instead of bitter) marmalade is to reduce the amount of white pith, seeds, and membranes.

4 tips to make your marmalade great

But first, you gotta pick the right fruit. Historically, and even today, the best fruit for the job is a Seville orange, a sour-bitter variety that's used as a souring agent in many Caribbean and Latin American cuisines in lieu of lemons or limes.
