Lupini preparation:
Day 1: Soaking the lupini
Sort and rinse your lupini beans. You need to get rid of any blemished or discolored beans.
Soak the lupini beans for 24 hours in cold water, so that they may become reconstituted.
Place them in a glass bowl, ensuring that they are submerged by a few inches of water. Lupini can be kept on the kitchen counter at room temperature.
