Cut tofu into 3/4 inch slices
Season boiling water with salt and cayenne pepper.
Place tofu in baking dish. Pour water over tofu and let sit for 15 minutes.
Remove tofu, place on cloth (waffle towel works well) or paper towels and drain for 15 minutes. Cover tofu on both sides, making sure to gently press out the moisture.
Using a non-stick pan, put grapeseed oil in frying pan. Using medium heat, get pan hot. Cover tofu pieces with corn starch, only right before you pan fry or tofu will get too much moisture. Fry for a few minutes on each side until golden brown.
Remove to plate with paper towels and immediately brush with sriracha sauce on each side.Rub sriracha onto the tofu, while it is still hot. Serve immediately.
To make sliders, use soft mini white rolls or use white bread, cut into circles or squares, no crust.
Serve with bread and pickles.
