Follow recipe for Salt Cure for Fish on its own page. Cure for 18-24 hours depending on thickness. 1/2 inch would be on the 18 hour side of the scale. 1 inch would be on the 24 hour side. You really just have to develop a knack for it through trial and error.
Slice thin and use however you want. Try with cream cheese and avocado on a bagel. You can also try like my cured scallops (served with citrus sauce and avocado).
SALT CURE: Makes mix per 1lb of fish to cure....3 cups kosher salt...1 cup white granulated sugar...Rind from 3 whole citrus fruits (must use lemon; if you have orange, tangerine, lime or any other citrus, by all means use those too)...1. Combine salt and sugar in a bowl and mix together...2. Wash/scrub skin of each citrus fruit and towel dry...3. Microplane citrus rind from each fruit...4.

Place fish on salt mixture base...9. Cover fish with remaining salt mixture and pack tightly...10. Wrap fish/salt mixture in saran wrap and place in ziploc bag...11. Put fish in refrigerator for required time (based on fish cure recipe)...12. When done curing, unwrap fish and rinse under cold water...13.
