About the dish

The last stage before the sugar becomes caramel, and the stage that spun sugar and hard sugar work require. Erken reminds us that a couple of drops of lemon juice or a little glucose prevents the sugar from crystallizing — "graining."

How to make it

  1. 1

    Boil a moment more

    Boil the sugar a moment longer than to the small crack.

  2. 2

    Take the test

    Dip your index finger in cold water, then in the sugar, and immediately back into the water.

  3. 3

    Judge the sugar

    If the sugar snaps like glass, it has boiled to the large crack. Take the pot off the heat at once, for a few more seconds of boiling turns the sugar to caramel.

  4. 4

    Prevent crystallization

    To keep the sugar from graining, add a couple of drops of lemon juice or 1 tablespoon of glucose per kilo of sugar.

Changes from the original

No ingredient list in the original beyond the additions against crystallization; the technique is rewritten into steps in modern language. Grape sugar corresponds to glucose/glucose syrup.

Frequently asked questions

How do I know the sugar has reached "the large crack"?
Dip your index finger in cold water, then quickly in the sugar and immediately back into the water. If the sugar film snaps like glass, you are at the large crack.
What happens if I boil it a little too long?
Just a few more seconds of boiling turns the sugar to caramel. That is why the pot must be taken off the heat immediately when the test shows the large crack.
How do I keep the sugar from graining?
Add a couple of drops of lemon juice, or 1 tablespoon of glucose per 1 kg of sugar.
Where does this instruction come from?
From Henriette Schønberg Erken's "Stor kokebok" (Great Cookbook) (1914), p. 449, in the section on sugar work and decoration.
