Remove the pit from the date and using the cutting board and knife, chop the date into small pieces. Put the date pieces in a single layer in a small, microwavable bowl.

Pour ¼ cup of water over the dates, making sure all the pieces are covered. Microwave the dates and water for 3 minutes, checking every so often to make sure the mixture isn’t bubbling over the sides of the bowl.

Once done, remove the bowl from the microwave (carefully if it’s hot) and use a fork to mash up the dates and remaining water. Keep mashing until the large chunks are gone and a thick paste is formed.

Pour the date paste into a small food processor or a larger bowl you can use an immersion blender with. Measure out the mayo, apple cider vinegar, and kosher salt put it in with the date paste. Blend until it has a creamy consistency.

Store it in a jar with a tight lid in the fridge until use.
