flax seed egg
from Vegan Planet
This is one of the best egg replacers I know. Mimics the consistency exactly; binds perfectly; imparts almost no taste -- and you're getting your daily dose of omega-3 fatty acids!
Grind the flax seeds in your roommate's coffee grinder until they're a fine powder. Then add the water. It will be liquidy -- but don't despair! Wait a minute, and the look at it again. Now it's all egg-y! Wow!
