Add lemon zest and lavender to pancake mix and follow instructions on the box to make pancakes.

In a medium saucepan, bring the blackberries, sugar, honey, and water to a boil. Reduce heat and simmer until berries are falling apart and sauce has thickened just a bit, 20 to 25 minutes.

Strain the sauce through a fine mesh sieve, pushing to extract all of the liquid from the berries. Transfer to the refrigerator; sauce will thicken as it chills. Store in an airtight container in the refrigerator for up to two weeks.
