Grind the dehydrated yuzu peel in a food processor to flakes or a fine powder, then sift.
Mix the peel with the salt. Add about 1 tsp black pepper per 100 g salt, if using. This is yuzu-shio; the ratio is 1:10 peel to salt.
Toss roasted nuts with the yuzu salt after roasting, as a finish. To season before roasting, toss the raw nuts with it and roast at 160°C for 15–20 minutes, stirring halfway.
Yuzu Kosho
Toss the raw nuts with the oil, yuzu kosho, and a pinch of sugar if you want to soften the salt. Yuzu kosho is already salty, so add no extra salt.
Roast at 160°C for 15–20 minutes, stirring halfway.
Yuzu Juice And Salt
Mix the yuzu juice, salt, and black pepper into a paste.
Toss the raw nuts with the oil and the paste.
Roast at 160°C for 15–20 minutes, stirring halfway. The juice cooks off and leaves a yuzu-salt crust.
Notes
Pick one section per batch. All three are ways to season nuts with yuzu.
Yuzu salt keeps as a seasoning. Scale the 10 g peel to 100 g salt ratio as needed.
