Place the tomatoes, jalapeno (whole, but stem removed), onion (chopped into 1" wedges), and garlic cloves on an aluminum foil-lined baking sheet.
Broil on high for 5 minutes before checking for black spots. The turn the garlic, which will likely blacken first, and broil for another 2 before removing ONLY the garlic.
Continue roasting everything else, turning over once or twice if needed, until you see substantial charring. The tomatoes should explode and wilt, and everything will get a few black spots.
Remove from the oven and let cool for 10 minutes before proceeding.
Place everything, and all remaining ingredients, into your food processor and pulse to your desired consistency. Taste, and add more salt or honey if needed.
Store in an airtight container in the refrigerator.
Notes
If you need a milder salsa, take the seeds and pith out of the jalapeno!
