My tips:

-
- People who don’t like capers can add fresh nasturtium to the potato salad. This also gives it a slight kick.
- If you don’t like raw onions, you can replace them with a bunch of spring onions.

Product description:
Capers are the flower buds of various caper plants and, when preserved in vinegar, oil or brine, are classified as a spice. Their nutritional content naturally depends on the preservation method. They contain many vitamins and minerals. Just like mustard or cress, they contain healing mustard oils that can help prevent all kinds of infections. The high price of capers is due to the labour-intensive production process. This explains why, in the past, the flower buds of other plants, such as nasturtium, were often processed into so-called false capers.
