The Soul of Summer: Crafting Rich Roasted Tomato Stock

I remember one sweltering August afternoon, standing in my tiny kitchen, surrounded by an abundance of ripe, sun-kissed tomatoes from the farmer’s market. I had made enough sauce to last through winter, jam to spread on every breakfast toast, and still, more boxes overflowed. It was then, amidst the fragrant sweetness, that I thought of a way to capture that very essence of summer, not just as a preserve, but as a foundational flavor. This roasted tomato stock, with its deep, concentrated essence, became my secret weapon, a liquid gold that could elevate any dish from ordinary to extraordinary, a true taste of sunshine captured for any season.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 1 hour 15 minutes (45 minutes roasting + 30 minutes simmering)
• Total Time: 1 hour 30 minutes
• Servings: 6 (approximately)
• Yield: 3 pints
• Dietary Type: Vegan, Gluten-Free, Dairy-Free

Ingredients

• 20 Italian plum tomatoes
• 1 teaspoon salt
• 1 teaspoon cracked black peppercorns
• 2 tablespoons olive oil, divided
• 1 medium leek, chopped (white and light green parts only)
• 2 medium carrots, chopped
• 1 large onion, chopped
• ½ lb mushrooms, chopped (any variety will work)
• 4 garlic cloves, chopped
• 1 cup dry white wine
• ¼ cup tomato paste
• 3 bay leaves
• 1 sprig fresh parsley
• 1 sprig fresh thyme
• 6 cups water

Equipment Needed

• Large baking dish
• Large saucepan or Dutch oven
• Fine-mesh sieve or food mill
• Saucepot
• Canning jars and lids (for preserving, optional)
• Pressure canner (if canning)

Instructions

1. Begin by preparing the tomatoes. Cut the Italian plum tomatoes in half lengthwise.
2. In a large baking dish, combine the halved tomatoes, salt, cracked black peppercorns, and half of the olive oil (which is 1 tablespoon).
3. Roast the tomatoes uncovered in a preheated oven at 375 degrees F. Allow them to bake for about 45 minutes, or until the tomatoes are visibly soft and their juices have begun to release.
4. While the tomatoes are roasting, heat the remaining olive oil (1 tablespoon) in a large saucepan or Dutch oven over medium heat.
5. Add the chopped leek, chopped carrots, chopped onion, chopped mushrooms, and chopped garlic cloves to the saucepan.
6. Cook, stirring occasionally, until the onion is softened, which should take about 8-10 minutes.
7. Stir in the dry white wine, tomato paste, bay leaves, fresh parsley sprig, and fresh thyme sprig. Cook for another 2 minutes, allowing the wine to reduce slightly and the flavors to meld.
8. Pour in the water to the saucepan. Bring the mixture to a simmer, then cover and cook uncovered for about 35 minutes, or until the vegetables are tender.
9. Once the tomatoes have finished roasting, carefully add the roasted tomato mixture (including any accumulated juices) to the simmering vegetable mixture in the saucepan.
10. Simmer uncovered for an additional 5 minutes, allowing the flavors to fully combine.
11. Now comes the magic of extracting the essence. Press the entire mixture through a fine-mesh sieve or a food mill into a clean bowl or pot. Discard the pulp and solids left behind in the sieve. This process will yield a rich, clear stock.
12. Pour the strained tomato stock back into a clean saucepot.
13. Bring the stock to a gentle boil over medium heat.
14. Once the stock has reached a gentle boil, remove it from the heat.
15. For canning: Ladle the hot stock into prepared jars, leaving a 1-inch headspace. Process the jars for 20 minutes at 10 lb pressure. Remember to adjust the pressure according to your altitude and the style of your canner for safe preservation.
16. For immediate use or refrigeration: Let the stock cool slightly before storing in airtight containers.

Expert Tips & Tricks

• Tomato Selection is Key: While any ripe tomatoes will work, Italian plum tomatoes are ideal for their meaty texture and lower water content, resulting in a more concentrated flavor. If you have a glut of other ripe tomatoes, don’t hesitate to use them, but be aware the yield might be slightly different.
• Don’t Rush the Roast: Roasting the tomatoes first concentrates their natural sugars and develops a deeper, sweeter flavor profile. A slight char on the edges is a good thing!
• Leek Prep: Ensure you thoroughly wash the leeks to remove any grit, especially between the layers.
• Sieve Power: A food mill is excellent for a super smooth stock, but a fine-mesh sieve with a sturdy spoon or spatula will also do the job admirably. Press firmly to extract as much liquid as possible.
• Herb Bouquet: Tying the parsley and thyme sprigs together with kitchen twine before adding them to the pot makes them easy to remove later, preventing stray leaves from clouding your stock.
• Cooling for Storage: If you’re not canning immediately, ensure the stock is completely cooled before transferring it to airtight containers for refrigeration or freezing. This helps prevent spoilage and maintains quality.

Serving & Storage Suggestions

This roasted tomato stock is incredibly versatile. Serve it hot as a starter soup, perhaps garnished with a swirl of crème fraîche (or a dairy-free alternative) and a sprinkle of fresh basil. It’s the perfect base for risottos, stews, braises, and sauces, adding an unparalleled depth of flavor.

• Refrigeration: Cooled stock will keep for 3-4 days in an airtight container in the refrigerator.
• Freezing: For longer storage, freeze the cooled stock in freezer-safe containers or ice cube trays. Frozen stock will maintain its quality for 3-6 months. Ice cube trays are fantastic for portioning out smaller amounts for quick flavor boosts in weeknight cooking.
• Reheating: Reheat gently on the stovetop over low heat until warmed through. Avoid boiling vigorously once reheated, as this can diminish the flavor.

Variations & Substitutions

• Smoky Undertones: For a subtle smoky flavor, you could roast the tomatoes under a broiler for a few minutes, watching carefully to prevent burning, before the oven roasting.
• Herb Garden: Feel free to experiment with other robust herbs like rosemary or oregano, adding them during the simmering stage. Remember to remove woody stems before straining.
• Vegetable Powerhouse: This stock is a great way to use up other odds and ends from your vegetable crisper. A parsnip or a celery stalk can add another layer of complexity. Just ensure they are chopped similarly for even cooking.
• Wine Alternative: If you prefer not to use wine, you can substitute it with an equal amount of vegetable broth or water, though the wine adds a unique brightness.

FAQs

Q: Can I use any type of tomato for this recipe?
A: While Italian plum tomatoes are recommended for their texture and flavor concentration, other ripe, fleshy tomatoes like Roma or even beefsteak can be used. Just ensure they are well-ripened for the best taste.

Q: How long does it take to roast the tomatoes?
A: The tomatoes should be roasted uncovered in a preheated oven at 375 degrees F for about 45 minutes, or until they are soft and their juices have started to release.

Q: What is the purpose of pressing the mixture through a sieve?
A: Pressing the mixture through a fine-mesh sieve or food mill separates the rich liquid from the solids, resulting in a clear, smooth stock. The pulp is discarded.

Q: Is this recipe suitable for freezing?
A: Absolutely! This roasted tomato stock freezes beautifully. Cool it completely and store it in airtight containers or ice cube trays for easy portioning.

Q: Can I make this stock without wine?
A: Yes, you can substitute the dry white wine with an equal amount of vegetable broth or water. The wine adds a distinct brightness, but the stock will still be delicious without it.
