Pro Tips
- Simmer the sauce low and slow for 10-15 minutes after it comes to a bubble — this is what concentrates the tomato paste and turns thin liquid into a thick glaze.
- If the finished sauce is thicker than you like, whisk in a tablespoon of water at a time until it reaches pouring consistency; it thickens more as it cools.
- For an extra smooth texture, blend the cooled sauce with an immersion blender before storing.
- Adjust the heat with a pinch of cayenne for more fire, or cut the chili powder back for a milder sauce kids will eat.
- Store the cooled sauce in an airtight container like a mason jar and it keeps in the refrigerator for up to one week.
