If you want to make the burger buns yourself: For 7 hamburger buns, you will need: 1 pack of white bread mix with yeast (450 g), 10 g of beet powder, 25 g of butter, 300 ml of lukewarm water, 1 egg, sesame seeds and / or poppy seeds. Preheat the oven to 200 ºC. Mix the beetroot powder into the bread mix and add water and butter. Knead and let rise according to the instructions on the package. Divide the dough into 7 equal pieces and roll into balls. Shape them into balls by rolling the dough in the hollow palm of your hands. Place them on a creased baking tray. Brush them with water or lightly beaten egg and sprinkle with sesame seeds and / or poppy seeds. Let them rise again to double volume and bake them for approx. 15 to 20 minutes. They should sound hollow when tapped.
Slice the onion into rings and the radish thinly. Marinate both with lime juice.
Make the fennel ‘slaw’; thinly cut or grind the fennel and the apple and mix with a spoonful of mayonnaise and finely chopped fennel greens. Season with salt and pepper. Mix the remaining mayonnaise with finely chopped tarragon.
Toast the bun halves on a (grill)pan. Generously spread the beet spread on the buns. Place the beet leaf lettuce and tarragon mayonnaise on top.
