For the basic mix: Line a baking tray with baking paper. Preheat the oven (electric cooker 200°C/circulating air: 180°C). Whisk eggs and milk in a bowl. Spread the egg mix in two bowls. Grate Gouda and divide it between the bowls.
For the ham eye sticks: Fry diced ham in a small pan without fat until crispy. Clean and wash the spring onions, dab dry and cut into fine rings. Grate parmesan. Put spring onions and parmesan in one of the two egg mixing bowls. Cut all spring onions lengthwise. Press them apart slightly and fill two of them with the egg and cheese mixture and the spring onions. Sprinkle ham over them and place on a baking tray lined with baking paper.
For the Caprese poles: Wash the cherry tomatoes, cut them in half. Cut the dried tomatoes into small pieces. Pluck the mozzarella finely. Stir everything into the rest of the base mix. Fill the remaining pretzel sticks with it and place them on the baking tray.
Bake all pretzel sticks in a hot oven for 8-10 minutes. Wash basil, shake dry, pluck off the leaves and chop coarsely. Wash the chives, shake dry and cut into fine rolls. Remove the sticks from the oven. Sprinkle the caprese sticks with basil and the ham sticks with chives.
