Ketchup with a side of fries

If your kid eats ketchup with a side of fries, this one's for you. We made a two-gallon batch in the school kitchen. At home, one small can of tomato paste gets you about a cup and a third.

Whisk everything together cold, bring it to a gentle simmer and give it five minutes. Then check the thickness. A little water loosens it. A little more time on the stove thickens it.

Let it chill before you make the final call on the flavor. A little honey if it's too sharp, a splash of vinegar if it's too sweet. You can also use a cup of it in the barbecue sauce for chicken tenders, or mix some into Epic burger sauce.

Instructions

Whisk and simmer

  1. Whisk all the ingredients together in a small heavy saucepan while cold. Break up the tomato paste until the mixture is smooth.
  2. Bring to a gentle simmer over medium-low heat, then lower the heat. Simmer for 5 minutes, stirring and scraping the bottom so it does not catch.
  3. If it needs smoothing, use an immersion blender with the blade fully submerged. Tilt the saucepan carefully if needed to give the blade enough depth.
  4. Check the finished amount in a heatproof measuring jug. Aim for about 1 1/3 cups. If there is more and it tastes thin, return it to the pan to reduce a little. If it is too thick or the yield is short, whisk in water a teaspoon at a time.
  5. Let it cool, then refrigerate until chilled. For the most settled flavor, leave it overnight before making final adjustments. Taste and add a little honey if too acidic, vinegar if too sweet or water if too thick.

Recipe notes

  • The spices are tiny in this batch. Keep the cloves and cinnamon to very small pinches so they stay in the background.
  • The five-minute simmer follows this week's school batch. Thickness is the better guide than extra time on the stove.
