Chickpea is the most common in the community. I'd caution to be careful with the salinity of the chickpeas, which can vary between vendors.

Hmm I wonder whether no sodium would make it better for sweets. Chia seeds seem good for sweets though too.

Recipes for sweet things usually include some salt because it enhances the flavor. If you've got salty chickpea juice, just consider reducing the other salt.
