Combine Ingredients:

In a medium saucepan, combine all the ingredients except for the lemon juice. Whisk together until well combined.

Simmer:

Bring the mixture to a simmer over medium heat. Reduce the heat to low and let it simmer for about 20-25 minutes, or until the mixture has reduced by about a third.

Add Lemon Juice:

After simmering, remove the saucepan from the heat and stir in the lemon juice.

Strain:

Strain the mixture through a fine mesh sieve to remove any solids.

Bottle and Store:

Transfer the strained sauce into a bottle or jar and allow it to cool completely. Seal and store in the refrigerator. The sauce will continue to develop its flavors over the next few days.
