"Milk adds something to the taste of a drink that is so right, yet so unidentifiable. And the sour note of the buttermilk picks up the lemon and lime perfectly in this cocktail."
2 ounces Patron Silver tequila
1 ounce buttermilk (organic non-homogenized did not separate)
2/3 ounce lemon juice
1/3 ounce lime juice
2/3 ounce agave syrup (use less for greater thickness)
1 bar spoon quince jelly
Add all the ingredients and ice into a shaker and shake until combined and chilled. Strain into a coupe.
