Nonc’s Mustard Quail Eggs are sold throughout South Louisiana and can be bought online at
Cajungrocer.com. The chopped jalapeño from the jar does add a bit of spice, so leave it out if your guests like a tamer potato salad (or make two batches). I like making this the day before and let the flavors hang out overnight. And as with any mayonnaise or egg-based food, keep this dish refrigerated until just before serving.
