Gummy Bears Without Corn Syrup or Dye — The Recipe That Finally Worked

Table sugar is sucrose, and sucrose wants to be a crystal. In a thick syrup it stays dissolved under protest. As water leaves a curing gummy, the molecules find each other again and lock into grit. Corn syrup interrupts that. It is mostly glucose in chains of different lengths, and those chains physically get in the way. Nothing can line up neatly around them.

Invert sugar does the same job from another direction. Heating sugar with a little acid splits each sucrose molecule into its two halves, glucose and fructose. Those halves are just as obstructive. Honey is already inverted, which is why a jar of honey never turns gritty on its own, and it would work here. It would also taste of honey at 55 g.

Bought tapioca syrup swaps in at the same weight with almost no flavour of its own. Brown rice syrup does too. Both cost several times what sugar and water cost. Cooking your own takes 25 minutes and yields about 380 g, which covers seven batches and keeps six months in the fridge.

Do not stir it once it is simmering. Stirring drags sugar crystals off the pan wall back down into the syrup, and one seed crystal is enough to turn the whole jar grainy as it cools.

Weigh 300 g caster sugar and 150 g water into a small heavy pan. Add 1 g citric acid, or 10 g lemon juice if that is what the house has. Bring it to a simmer without stirring, then hold it between 105 and 110°C for 20 minutes. Brush the inside wall of the pan down with a wet pastry brush every few minutes. That washes stray crystals back in before they can seed anything.

It is ready when a drop cooled on a cold plate is thick like warm honey and still clear. Pour it into a clean jar while it is hot. Cold invert syrup does not want to leave a pan.

260 g of tart cherry juice down to 150 g is a 42 percent loss of water. The colour concentrates by the same amount. That reduction looks too dark in the pan, which is roughly right, because 30 g of pale gelatin is about to dilute it.

Red and purple fruit colours come from anthocyanins, a group of pigments that shift shade with acidity. More acid pushes them red. Less acid pushes them towards grey and blue. Long heat dulls them whatever the acidity is doing, which is why the citric acid goes in at the very end and the reduction gets the shortest boil that will do the job.

Other colours are available and every one of them is duller than dye. 2 g of beetroot powder gives a clean pink that visibly fades inside a week. 3 g of freeze-dried raspberry powder holds on longer. Turmeric at 0.5 g gives yellow; at 1 g it gives yellow plus a taste of turmeric. Spirulina makes a green that also tastes of spirulina, so stay under 1 g. Blue is not happening without butterfly pea flower, and butterfly pea turns pink the second the citric acid lands on it.

Pick two colours for a batch. Each one needs its own pan of reduction, and the first bowl is setting while you are still dividing up the second.

30 g of gelatin to 205 g of liquid works out at about 15 percent. The liquid there is the 150 g reduction plus the 55 g of syrup. Use 200 bloom powder, bloom being a strength rating, and 200 is what most supermarket sachets are.

Under roughly 12 percent the mix still sets, but the bear sags. Ears round off overnight and the feet spread out. Over 18 percent it turns rubbery, and a rubbery gummy takes a hard bite and then springs straight back at you. The window between those numbers is wider than it sounds, so anywhere from 14 to 16 percent is comfortable.

Scatter the powder across the cold reduction rather than tipping it in. A dumped heap forms a lump with a dry core, that core never dissolves, and it finishes up as a gritty speck inside a finished bear. Ten minutes of blooming is plenty at this ratio.

And leaf gelatin works, if leaf is what you have. 30 g of powder is about 17 gold-strength leaves at 1.7 g each. Soak them in plenty of cold water, then squeeze them out hard, because whatever water they carry in thins the reduction you just spent 12 minutes making.

Straight out of the mould a bear holds around 22 percent water. A shop-made one sits nearer 15. That gap is the whole difference between something soft and wobbly and something that chews.

Space them out on a wire rack at room temperature for 24 to 48 hours, turning them once on the second day. The fridge is the wrong place for this part. Fridge air is damp, and a damp bear never loses the water it has to lose.

Humidity in the room decides how long it takes. Above about 60 percent they stop drying and go tacky instead. A small fan aimed past the rack fixes that faster than extra hours will. An airing cupboard is too warm; they slump, and the ears go first. Cool and dry beats warm and dry here.

A sour coating is optional, and it goes on after curing. Mix caster sugar and citric acid at 1:1 by weight, then toss the cured bears through it a handful at a time. Coat one that is still damp and the sugar dissolves into syrup on contact.

There is no preservative in this and no control over water activity, which is the measure of how much free water a microbe can get at. In an airtight jar in the fridge, two to three weeks. On a shelf at room temperature, about five days before the surface turns tacky.

Mould shows up as fuzzy white or grey spots, and it starts where two bears were touching. One spotted bear means the jar goes out, not just the bear. Freezing is no way around any of it, since they come back grainy from the thaw.

Make the full 120 and get through them inside a fortnight. If that sounds like a lot of bear, halve every number on the list; the ratio survives being cut in half, and 60 bears is about a week.
