Soak.Add the chickpeas to a clean bowl and top them with a good couple of inches of cold water. As they are soaking up the water, they will expand, so using plenty of water is essential. Leave them out on the countertop to soak for 8-12 hours or overnight.
Rinse and Drain. Rinse and drain them over the sink using fresh, running water using a sieve/strainer. You might give your chickpeas a little shake and a stir whilst you're there to help them aerate. Look them over and remove any that are split, damaged, discoloured or that have dark spots and discard those. Chickpeas can spoil relatively quickly, so it's important to rinse and drain them well every 8-12 hours (morning and evening), to help them stay fresh and clean. Gently throw off any excess water and leave them spread out in the sieve, placed over a bowl to catch the drips. This allows air to circulate underneath.
Sprout. The sprouting process takes 2-4 days and needs only 2 minutes of your time each day until grown and ready to use. Leave away from direct sunlight to sprout, and cover them with a piece of kitchen paper to keep any little bugs away. Rinse and drain your sprouting chickpeas 2-3 times each day with cold water.
Harvest. You can harvest your chickpea sprouts when they have germinated and the tails are just a few millimetres long, the width of the chickpea or more. Once sprouted, give your chickpeas one last thorough rinse and drain. Remove and discard any that are discoloured, that have dark spots or look odd to you.
