This is perhaps too simple to be called a recipe- it's nothing more than a simple way to make plain extra-firm tofu into something a little more... snackable. It's hard to go wrong with anything fried, and these have the added benefit of the protein and vitamins of tofu, making it easier to justify them... Obviously, I'm not advocating for you to fry all your tofu, but it beats chips in more than a few ways if crispy and golden-fried is what you're after.
I call them croutons because they make salads a bit more exciting if you add them in, rather than traditional bread croutons. They've got a good mixture of crisp exterior and moist interior that melds well with a lot of additional flavours, as I detail in my variants.
For me, this is an ideal snack for when you're watching a movie or TV and want some finger food. This was actually something I made when I had leftover oil in a wok from frying other stuff I didn't want to go to waste- but it turned out to be really addictive for something you can make with the bare-bones basics whenever. Still, I plan to come up with recipes for soups and salads that call for croutons just to have an excuse to make more...
1 Lb. Extra-firm tofu, cut into 2-3 cm cubes
2 TBSP cornstarch or flour (rice flour would likely work fine as well)
Enough vegetable oil for shallow-frying in a skillet or wok (peanut or canola work great)
One of the following seasoning mixes:
Salt and Pepper: 2 Tsp. Salt plus 2 TBSP freshly ground black pepper
Garlic-Herb: 2 Tsp. Garlic salt (or 2 Tsp. Salt plus 1 Tsp. garlic powder) plus 1 TBSP herbes de Provence or Italian dried herb mix
Five-Spice: 2 Tsp. Salt plus 2 Tsp. five-spice mixture
Lemongrass-Chili: 2 Tsp. Salt plus 1 TBSP fresh or frozen minced lemongrass (not dried!) plus 1/2 TBSP red chili flakes
Heat the oil on medium-high heat, taking care for it not to smoke.
Toss the tofu cubes with the flour or starch. Add to the oil (carefully- don't let it splatter on you!) and fry until golden-brown, flipping and adjusting the heat as necessary to keep from burning.
Drain on paper towels or a metal rack to remove excess oil. Toss with the seasoning mixture of your choice and add a little more salt to taste.
