Even though condiments like mayo, salsa and mustard often come in recyclable glass or plastic containers, I like trying to take a step closer to zero waste by whipping up my own sauces in bulk. This not only gives more control over the ingredients, but also saves money on grocery bills, too!

Believe it or not, making a simple, homemade mustard is easy as 1, 2, 3.

What you’ll need:

• 5 tbs. mustard seeds
• 2 tbs. horseradish
• 2 tbs. salt
• ½ cup mustard powder
• ½ cup water
• 2 tbs. apple cider vinegar
• Reusable container

1. Grind the mustard seeds.
2. Pour the seeds into a bowl and stir in the mustard powder, salt and horseradish. Then add in the vinegar and water and mix well.
3. Transfer mixture into a container and refrigerate before serving.

Then, taste and enjoy! Try slathering your freshly made mustard on your sandwich this weekend.

By making your own mustard, the only waste you’ll produce from this recipe is the recyclable glass or plastic packaging for ingredients you probably already have in your cupboard: The mustard seeds, powder and vinegar. That means there’s nothing left for the trash can — and even more so if you compost your horseradish scraps, too!
