Tomato Purée

The secret to restaurant-level depth across sauces, soups, and reductions begins with a clean, unadorned tomato purée. By sweating sweet yellow onion gently in olive oil to release natural sugars before simmering ripe plum tomatoes and passing the emulsion through a fine-mesh tamis, this foundational purée achieves a high-gloss, ultra-silky texture. Left entirely free of herbs or heavy seasoning, it offers a pristine canvas of pure, concentrated fruit ready to elevate any bistro dish.

• 3.5 lb ripe Roma or plum tomatoes, quartered
• 1 piece sweet yellow onion, finely diced
• 3 tbsp extra virgin olive oil, divided
• 0.5 tsp fine sea salt

1. 1
   Sweat Aromatics

   Warm two tablespoons olive oil in a wide pot; sweat onions gently over low heat until completely soft and translucent.

2. 2
   Simmer Tomatoes

   Add quartered tomatoes and salt; simmer uncovered over medium-low heat, stirring occasionally until juices concentrate and skins slide loose.

3. 3
   Pass Through Mill

   Pass hot tomatoes through the finest disc of a food mill or fine tamis, discarding bitter seeds and skins.

   Emulsify & Cool

   Whisk remaining olive oil into warm strained purée until glossy; let cool before bottling this pristine pantry staple.

Chef’s Bistro Technique

Avoid using an immersion or jug blender on this purée. High-speed blades pulverize seeds, imparting bitterness and aerating the sauce into an undesirable chalky pink. Using a traditional food mill keeps the texture velvety and preserves the vivid red color.
