Put 340 ml of lukewarm water and the baking mixture into a mixing bowl. Knead with the dough hooks of the hand mixer at the highest setting for approx. 5 minutes to a smooth dough. Cover and leave to rise in a warm place for at least 30 minutes. Knead the dough again on a floured work surface and form into a long roll. Cut the roll into approx. 36 small pieces, form into balls and press them into flat talers by hand. Spread on 2-3 baking trays lined with baking paper, cover and leave to rise for another 15 minutes.
Meanwhile wash the herbs and shake them dry. Cut the chives into small rolls and pluck the remaining herbs into small pieces. Wash tomatoes, dab dry and cut into slices. Drain mozzarella and cut into slices. Season crème fraîche with a little salt and pepper. Cut 24 mini pizza bases crosswise with a knife and brush with water. Sprinkle 12 bases with some coarse sea salt and cover with the herbs. Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for 15-20 minutes. Spread 1/2 teaspoon of pesto on each of the remaining pizza bases and cover with 1 slice of mozzarella and tomato. Bake in the same way as the first pizza bases. In the meantime, place a teaspoon of crème fraîche on each of the 12 uncoated, still warm pizza bases and spread the salmon on top. Sprinkle with chives.
