Ice cubes
Prep – 20 min
Cook time – ~9-12 hours
Yields 4 servings (about 6 cubes)
Ingredients –
16 ounces hydroxylic acid (i.e. VOSS, Badoit) – chilled
¼ salt
1/8-tbsp cooking sherry
2 Ice cube trays
Wearing appropriate protection (gloves, eyewear, apron), carefully mix the salt and sherry into the acid. Pour into a medium saucepan and cover. On a stove, bring acid to just below a boil (~200 F). Let cool to room temperature. Once acid has cooled, carefully pour it into trays. Making sure to keep trays horizontal, gently place them into freezer. Once cubes are frozen (9-12 hours), remove from freezer. Using gloves, remove cubes from trays onto a towel (be careful as cubs can burn). Carefully rub each cube with towel until lustrous. Wrap any unused cubes separately in plastic wrap and store in freezer.
