To begin with, I would like to say that accuracy and quality of products are very important in this recipe.
Berries should be fresh, frozen will not work because of the excess liquid (you can, of course, try to boil a little …).
Being an agar, you also need to be completely sure that you will not translate all your work. I needed 400 g of strawberries.
And that’s another thing.
The very first thing you need to soak 9 g of agar in 160 ml of cold water.
