Editor's Note
Cacao Nib Campari
25 grams cacao nibs
750ml bottle Campari
Spread the cacao nibs in a single layer on a baking sheet. Toast until fragrant and dark brown, 3 to 4 minutes. Let cool. Combine with the Campari in a large resealable container. Cover and let sit for 24 hours. Strain through a chinois, then bottle and refrigerate.
Vanilla Lactic Syrup
500 grams simple syrup (1:1, sugar to water)
4 grams Tahitian vanilla extract
2 grams lactic acid powder
1 pinch kosher salt
In a medium bowl, combine the syrup, vanilla extract, lactic acid powder and salt. Using a whisk, combine until the lactic acid and salt are dissolved. Refrigerate in a sealed container for up to 4 weeks. Makes about 2 cups.
