Whole grain mustard is a mustard made with whole mustard seeds rather than the more common ground mustard powder.

The seeds are soaked in water and then ground into a paste, combined with vinegar, salt, and spices.

The resulting mixture is left to ferment for several weeks, allowing the flavors to develop and mellow.

Whole grain mustard has a distinctively sharp flavor that pairs well with various foods.

It can be used as a spread on sandwiches or as an ingredient in sauces and salads.

Whole grain mustard is also a popular choice for making homemade pickles.

The strong flavor of the mustard helps offset the sweetness of the pickling solution, resulting in a tastier final product.

Whether you're looking for a new condiment to try or simply want to add some extra flavor to your cooking, whole grain mustard is worth seeking out.

To substitute mustard seeds with wholegrain mustard, use an equal amount. For example, if a recipe calls for 1 tablespoon of mustard seeds, you would use 1 tablespoon of wholegrain mustard instead.

2 - Horseradish

It can also be eaten as a condiment or added to salads for a bit of zing.

Whether you love it or hate it, there's no denying that horseradish packs a powerful punch.

So the next time you want to add some spice to your meal, reach for the horseradish.

You might just be surprised by how much you enjoy it.
