No buttermilk? No problem. Put 2 tsp of white vinegar or fresh lemon juice in your 1/2 cup measure. Fill the rest with milk. Allow it to sit at room temperature for 10 minutes to thicken and turn into “homemade buttermilk”

Note: The original recipe calls for lemon and orange rind for a sunkissed finish. It certainly gives it je ne sais quoi. Personally, i prefer to replace this tablespoon of rind with lemon juice, as it provides a more smooth texture. But this is simply a personal preference so I encourage you to try both ways.
