Preheat your oven grill/ broiler to high.
Halve the tomatoes and place them on a lined (see my notes) baking sheet cut side up.
400 g miniature/baby tomatoes
Place them under the grill about 8 - 10 cm (3 - 4") below the element.
Grill for 6 - 8 minutes until they start to char and become soft and jammy.
Place tomatoes in the bowl of a small food processor, along with garlic, salt and pepper.
1 garlic clove, ½ teaspoon cooking salt, ¼ teaspoon fresh black pepper
Blend until mostly smooth, then allow to cool (see my notes).
Once cool, add herbs and softened unsalted butter to the processor.
2 teaspoons fresh thyme leaves, 1 tablespoon fresh oregano, 200 g unsalted butter
Blend until well combined, scraping down the sides as you go.
