Note from Ricardo
The buttermilk can be replaced with ½ cup (125 ml) milk mixed with 1 ½ tsp (7.5 ml) white vinegar or lemon juice. Let sit for 5 to 10 minutes. Stir before adding to the recipe.
These doughnuts make a great gift. Simply replace the white chocolate cream with 4 oz (115 g) melted and slightly cooled white chocolate. Dip half of each doughnut in the melted chocolate and place on parchment paper. Sprinkle with the pistachios and rose petals. Let the chocolate set before wrapping.
