1.
Pickle the shallot: Combine the rice vinegar, sugar, and a pinch of fine sea salt in a small bowl, stirring until the sugar dissolves. Add the sliced shallot and let it sit for at least 20 minutes, until the rings turn pale pink and lose their raw bite.
2.
Slice the sea bass: With a very sharp knife, slice the fillet as thin as you can manage, on a slight angle, so light passes through each piece.
3.
Lay the slices out on a chilled plate in a single layer, slightly overlapping.
4.
Sprinkle fine sea salt evenly over the fish, then squeeze the lemon juice over the top, followed by Noor Fès olive oil.
5.
Drain the pickled shallot and scatter the rings over the fish, along with the sliced chili. Add a pinch of flaky sea salt and the purple basil microgreens.
6.
Dress and plate crudo as close to serving as possible, so the fish stays firm and every flavor stays distinct instead of blurring together.
