1. Center a rack in oven and heat to 400 degrees.
2. Remove stems (plus seeds, as desired) from hot peppers and pepperoncini, then place on a baking sheet along with garlic. Drizzle with olive oil and season with 1 tsp. salt. Roast until peppers are softened and begin to blister and char around edges, about 20 minutes.
3. Let cool 5 minutes, then transfer to a blender. Add vinegar, water, honey (if using), and mustard and puree until smooth. Season with more salt to taste. Store in an airtight container in the fridge for up to 3 months.
