Still Life: the recipe, the solution

I'm playing Still Life...
In the game you are a girl so "why don't put in the game a cooking enigma??"

This is the recipe and the ingredients (put mouse over elements to identify them):

In the bowl put:

- 1/2 cup of BUTTER
- 1 cup of SUGAR
- 1 cup of MILK

mix

- 2 cups of FLOUR
- 1 tablespoon of GINGER
- 1 teaspoon of CINNAMON

mix

- 1 EGG
- 1/2 cup of MELASSES

mix and put in the oven!!

Oh Jesus! I'm now on the lock-picking enigma... WHAT THE HELL.
