Fermented Blueberry Jalapeño Scallop Crudo Recipe

Scallop crudo with fermented jalapeños.

Not only do these fermented blueberry jalapeño slices add a deep purple pop of color to both sweet and savory dishes, but they also contribute a tangy and sweet lingering heat.

The ferment starts by slicing jalapeños quite thin. The slices are then combined with frozen blueberries, apple juice, apple cider vinegar and a salt brine and left to ferment at room temperature for one week. The flavor continues to develop even more when left in the refrigerator for a number of weeks.

Since the fermented jalapeño slices offer such a multi-dimensional spectrum of flavor, they are the perfect topping for a plate of seafood crudo. They cut through the richness of the scallops and are small enough to get a slice in each bite. The combination pairing of the lemon oil, blueberry flavor notes and fresh basil topping makes this dish a winner.

What’s Good to Know with Chef Olivia:

  • Always leave the seeds intact when fermenting jalapeños, as the flavor will otherwise be bland and quite flavorless.
  • Mince and use extra fermented blueberry jalapeño slices as a mignonette topping for a platter of oysters.
  • Use the fermented blueberry jalapeño brine to craft next-level margaritas.
  • Try thickening the fermented mixture with pectin to create a spicy blueberry jalapeño jam.
  • Pair fermented blueberry slices with anything corn such as elote, cornbread or a topping for nachos.
