sugar foam

tutorial for sugar foam

For my next cake, I have already prepared part of the decoration today. After a long time I made this cool sugar foam again and thought I would share the recipe with you. It works really easy with only two ingredients and the effect is just great.

You only need 1-2 tablespoons of glucose syrup* which you heat up for 20s at 600 watts in the microwave to liquefy it a bit.

This makes it easier for you to colour it with food colouring*. I have used teal*, violet* and pink*.

Then you can simply spread it thinly on baking paper with an angled spatula*. The thinner, the more holes you will get in the foam and you can achieve different effects by varying the thickness between 1-3mm.

Now put the glucose syrup* in the oven at 160°C for about 45 minutes and you will see how the bubbles form after a few minutes.

A few minutes after you have taken the foam out of the oven, it has already cooled down and you can carefully remove it from the baking paper. The foam is relatively stable, depending on its thickness, but it should be prepared no more than 2 days before the cake is served, otherwise the bubbles will dissolve again when they draw humidity from the air.

    Can you drape this over the side of the cake? I mean, is it flexible once it cools? Or brittle?

    Hi Alan,
    it will get hard, so wrapping it will be difficult but you can use small pieces or put it on Top.

    Hi Dorthe,

    you can also heat it on a double boiler or a pot but on very low heat. It should just get a Luke but more liquide so you can spread it better.

    I'm curious about one thing. How much will the 1 to 2 tablespoons of glucose syrup yield? Still the same, 1 to 2 tablespoons or one of the colored circles of bubbles shown in pictures?

    Hi Pamela,

    it depends on how thick you spread it but it is about 2 big or 3 small foam pieces. I choose this amount to fit good on a baking try.

    Let me know if you have more questions.
    Regards Bettina

    I just left it on the table, covered with a bowl. Humidity is not good for it an cling wrap is also not a good idea because it sticks to it.
