Instantgel

Fruit is the ingredient most likely to ruin the product it is in. It bleeds into sponge, softens pastry, weeps under a glaze and slides out of a cut cake. Instantgel is the small, unglamorous product that stops all of that.

What it is

A powdered gelling and stabilising agent for fruit purées that sets cold. Add it to the purée at six to twelve per cent of the purée's weight, disperse it, and the fruit becomes a filling or a glaze with a defined body instead of a liquid with flavour in it.

The percentage is against the fruit

This is the important detail and the one most easily got wrong. The dosage is a percentage of the purée, not of the finished batch and not of the total recipe. It scales with the fruit.

That makes it different from almost everything else on the bench, where a dosage is quoted per litre of something. Weigh the purée first, calculate from that number, and write the method down in those terms — a production sheet that records "60 grams of Instantgel" instead of "six per cent" stops being correct the first time somebody changes the batch size.

Choosing a percentage

Six per cent gives a soft, spoonable set: right for a layer inside a filled pastry, or a glaze that has to flow before it holds. Twelve gives a firm set that will take a clean cut, which is what a layered cake needs if the fruit layer is going to survive being sliced in front of a customer.

Between those, the fruit itself decides. High-acid fruit — passionfruit, citrus, the Australian natives that are worth using — behaves differently from a low-acid purée at the same percentage, and water content varies enormously between commercial purées and fruit broken down in-house. Trial each fruit, and re-trial when the season moves. A figure carried across from mango to raspberry is a guess.

Why cold setting matters

A cooked set costs you the fresh aromatics that made the purée worth using. Heat drives off exactly the volatile compounds that distinguish a good raspberry from a red one, so a fruit filling that has been boiled to set it tastes like jam rather than like fruit — which is fine if jam is what you wanted, and a waste of good purée if it is not.

Setting cold keeps the top notes and takes the preparation down to minutes.

Where it fits

Fruit fillings for tarts and layered cakes; glazes that hold shine and slow moisture loss in a display cabinet; stabilising a purée that has to sit next to sponge or pastry without soaking into it. It is also the honest answer to a fruit layer that keeps sliding out of a finished cake, which is usually a set problem rather than an assembly problem.

For a fruit coating over a frozen product rather than a filling, the product you want is a covering, which sets by temperature rather than by gel.

Handling

Keep the pack sealed and dry. A powdered gelling agent that has taken up moisture clumps, and a clump that does not disperse becomes a lump in a finished product where it is highly visible. Disperse into the purée while mixing rather than dumping and then stirring.

What we do not publish

Ingredients, allergens, shelf life and storage conditions are absent from this page because no Elenka specification sheet is held for the Australian range. Absent means the data is not held, never that the answer is no. Request the sheet for any product you are considering and we will obtain it from the manufacturer.
