Preheat oven to 275 degrees. Add a sheet of parchment paper to medium sized rimmed baking pan. Add thyme branches – top with tomatoes, cut side up. Drizzle all over with olive oil. Sprinkle with 1/4 teaspoon of salt.
Slow-cook for 45 minutes to 1 hour – this will depend on the size of your tomatoes. Look for: tomatoes that has shrunken, are condensed with only a drop of golden color around the edges… no more!
Make the Softened Garlic: Add 2 tablespoons of extra virgin olive oil to your smallest skillet (mine is 6″) Add 1 large or 2 medium sized garlic cloves – sliced 1/8 inch thick. Heat over the lowest heat and cook until softened – yet NOT golden, about 5 minutes. Set aside. Love garlic? You can double this amount if desired.
Add the softened butter to the small food processor (mine is a 4 cup one.) Pulse a few times to whip. Use a rubber spatula to scrape down, repeat. Add the remaining ingredients – the cooked tomatoes, 1/2 teaspoon of thyme from the pan (removed from a branch), 1/2 teaspoon fresh thyme leaves, the cooked garlic (not the oil) and 1/4 teaspoon of the remaining salt. Save the oil; great for salad dressing.
Blend until mostly smooth with small pieces of chopped tomatoes. The butter is ready to use! If you feel it is too soft, place in a small bowl and refrigerate a few minutes.
*I have chosen Vermont Creamery Cultured Butter (sold at my local Acme supermarket) – or source out Organic Butter which is readily available in most supermarkets. I DO NOT use butter with “natural flavorings” – in ALL commercial butters.
Store in a clean glass storage container in the refrigerator. Best used softened. Will stay fresh about 3 weeks. Can also freeze.
To make a Compound Butter Log: Cut a piece of waxed paper or parchment paper about an 8″ square. Add the butter to center, fold over the paper rolling into a tight log, twist the edges and refrigerate until very firm. When ready to use, slice a piece and add to warm foods… the butter will beautifully melt in.
