300g spent grains
Dry the grains in oven, 100°C for a couple of hours (you can do that the evening before, or after sparging).
Make a sugar syrup: add sugar and water and bring to boil, keep it boiling for 5-10 minutes, until it's enough dense.
Then add the butter and let it melt, mixing everything.
Add the dryed grains, mix with a spoon, and put the mix on a baking tray, heat the oven at 100°C for 30 minutes, then let everything cool down for some hours
Now you can cut or break it in small bars.
The recipe is quite easy, you cannot use the whole grain but is a cool and tasty snack, the perfect food to calm down the hunger after drinking too many beers...
