Take the butter out of the fridge about an hour beforehand.
Halve the sun-dried tomatoes and grate finely in a food processor (here Thermomix, level 5). The tomato pieces should be small enough, but not pulverized (under visual inspection).
Cut the butter into cubes and add the chopped tomatoes. Also add tomato paste, Worcester sauce and lemon juice. Season with pepper and paprika powder. Stir the entire mixture at the same level for about 10 seconds.
Finally add the olive oil and beat the mixture until creamy.
