HOW TO MAKE ROASTED TOMATO SAUCE
- How to roast tomatoes for sauce: Place ripe tomatoes into a large roasting pan or rimmed baking sheet. A variety of tomatoes will add even more flavor but using Roma tomatoes, cherry tomatoes or any one variety you can find is also fine. Make sure they are ripe to get the most out of them. Drizzle the tomatoes with olive oil and add garlic, herbs of your choice and a generous pinch of salt. Place the tomatoes in a hot oven and allow to roast until the tomatoes have released their juices and their skins are starting to blister.
- Make the sauce: In a large pot, fry onions and garlic in olive oil or butter until soft and translucent. Add the roasted tomatoes along with smoked paprika, dried Italian herbs, salt and sugar (optional). Turn the heat down and allow to simmer for 10-15 minutes until reduced. At this point you can break down the tomatoes with a potato masher or blend with an immersion blender until smooth. Season to taste then use or store for later.
HOW TO CUT ACIDITY IN TOMATO SAUCE
Tomatoes can be very acidic and the best way to cut the acidity is by adding a little sugar or sweetener. A neutral sweetener like sugar or xylitol works best as it doesn’t alter the flavor of the finished sauce at all.
