Let me clarify

Eggplant: sweat it for 60 minutes. Could do 45 minutes if you're pinched for time. Cutting boards won't produce a puddle and lead to more even results than sweating in a colander. A light layer of moisture will accumulate on top of the eggplant slices, and you absorb it with a towel or paper towel. The eggplant should feel dry before cooking.
