• In a heatproof bowl set over (but not touching) simmering water, mix together sugar, cornstarch, and salt. Add hot water and cook, 3 to 5 minutes, whisking gently, until thick.

  • Add the butter, lemon juice, and zest and continue cooking, stirring gently, for about 5 minutes. Cool slightly before using, but do not refrigerate (the sauce will become aspic-like) and do not reheat.

This recipe has far too much water; the sauce came out not like aspic at all, but more like very weak lemonade with a butter topping. There was not enough corn starch to thicken the amount of water in the recipe.
