Home-made Stir-Fry and Deep Fried Tofu

I made a stir-fry of string beans, mushrooms, and shredded carrot, sauteed in hoison sauce.  Then I deep fried some extra firm tofu and topped with sweet chili sauce.  The first batch was a little "well-done" haha, so it kind of looked like a dried sponge and wasn't so tasty.  The second batch was more edible.  I couldn't tell how cooked it was because the color didn't change that quickly.  I think that's what I get for deep frying it straight instead of breading in flour.  Next time I'll use flour.
