Experiment

Lingonberries are too sour to eat alone but too interesting to cook down into jam. What if I put them in an ice cream — no machine, folded cream — with aggressive black pepper?

Result

The pepper was the right call. It cut through the fat and amplified the tartness of the lingonberry rather than fighting it. No machine ice cream is softer and denser than churned — which worked better here. Failed experiment becomes a staple.
