Like you, I enjoy making hot sauces with my peppers. Everyone's getting some for Xmas! Typically, I prefer single variety sauces so that I can taste the pepper flavor. The family likes a serrano sauce that has the right amount of heat for them without being overpowering. Leaving whole or halfing and deseeding is up to you. Simply put them in a pot with water, kosher salt and a little white vinegar (do not like to taste vinegar in may sauce) and boil for 15 minutes. Adding a little onion and garlic never hurts. I then process in a blender (as opposed to a food processor) to a point where it resembles a thick slurry adding just enough of the cooking water to reach that consistency. I then strain through a fine mesh kitchen strainer to get rid of bits, pieces, seeds, etc. The finished sauce is thin but not watery. If you like a thicker sauce, I put the sauce back in the pot, bring to a boil and a little corn starch (NOT flour) and water mixture to thicken it up. Be careful, to much can make it like gravey. Bottle it up (if refrigerated) or can in a hot water bath. Seems to taste better the longer it ages.
For a sauce that has a tomato accent, I roast fresh tomatoes (preferably from the garden) over mesquite for 3 hours and then add that to the sauce before blending. This sauce is pretty thick from the start. I've done a carrots, tequila and hab sauce mentioned earlier that was pretty tasty. Experimentation is half the fun.
I'm a newbie too so welcome to the forum.
