Whats your favorite? Why is great?
I'm currently in love with All Spice Cafe's cayenne habanero sauce. Its hot but you can still taste the different types of peppers and spices in. Its got some nice up front heat with a only a medium lingering burn so you can still taste a whole meal. My (veggie) chicken nuggets are bathed in it.
yeah I usually BBQ everything before I blend, pretty much can pick any handful of ingredients and blend them well enough and it turns out good if you add the right amount of vinegar, salt, garlic, onion. hot sauces seem pretty hard to fuck up unless you get your ratios wrong. check a few recipes before you do your first one to get a good idea of what those ratios might be and then adjust for taste after you make a first batch.
