The Method
1
Bring a small pot of unsalted water to a full boil. Add the nettle tips and blanch for exactly 60 seconds — no longer, or flavour is lost. Drain, refresh briefly under cold water, and squeeze the nettles with both hands until completely dry. Roughly chop and set aside with the remaining prepared herbs. The nettles are ready when no water runs from them when pressed hard.
2
Break the eggs into a wide bowl and beat until the yolks and whites are fully unified. Add the dry Trebbiano d'Abruzzo and the fine sea salt. Fold in all the prepared herbs — wild fennel, borage, nettles, and wild garlic — so that the herb volume equals the volume of beaten egg. Grate the Pecorino d'Abruzzo directly into the bowl at this moment and fold through. The mixture is ready when the herbs are distributed evenly and no pocket of plain egg remains visible.
3
Set a cast-iron pan over the lowest possible heat and add the olive oil. When the oil shimmers but does not smoke, pour in the egg and herb mixture and spread it level with a spatula. This is where the dish lives or dies: maintain low heat without compromise for 8–10 minutes, allowing the base to set and turn golden slowly while the interior firms from the bottom up. A high flame browns the base before the interior can set, and the frittata will be raw at the centre. The base is ready to finish when the edges are fully set and matte and only the very centre carries a slight tremor.
4
Transfer the pan to a grill preheated to high. Cook for 2 minutes until the top surface is just set — no longer liquid, but still carrying a faint give when the pan is gently shaken. The top must not colour or firm completely; a slight tremor in the centre is correct. Remove immediately.
5
Slide the frittata onto a board and allow it to rest, uncovered, until it reaches room temperature. Wild herb flavours are most expressive at ambient temperature. Slice into wedges and serve. The interior should be cohesive and herb-dense, with no weeping liquid and no dry, crumbling texture.
