Put the flour, baking powder and the cold vegetable stock and soy milk in a sufficiently large bowl, stir well with the hand mixer for approx. 1 minute until there are no more lumps. Set aside and let rest briefly.
Finely dice the carrots and celery. Cut the spring onions into very fine rings. Add everything to the batter, including the soy sauce, with a spoon and stir. Season to taste and, if necessary, add salt or 1 tablespoon soy sauce.
Heat the oil in a pan and fry the dough in portions in the hot oil on both sides until medium brown.
This amount of batter makes 6 pancakes in a 24-hole pan.
Tip: A garlic or herb yogurt sauce also goes perfectly with it. If there are no uncomfortable children eating, you can easily increase the proportion of vegetables by half.
