Tips
- If you don’t want to turn on the oven, you can also caramelize the grapes in a small pan over low heat, but they turn out better in the oven.
- If you only want to make the soup as a starter, you can halve the ingredients or plan the rest for the next day.
- If you don’t want to go without meat or would like to add another flavor component, cook small meatballs made from salchicha sausage in the soup at the end. To do this, squeeze the meat out of the sausage casing and shape it into small balls.
- Storage: Keep the soup in the fridge for 2–3 days or freeze it without toppings for up to 3 months.
