FAQ
How much corned beef per person?
Corned beef loses weight when cooked, so plan on raw weight above the cooked portion. The calculator handles that for you.
Is the beer only for drinking adults?
Yes. Stout and other alcohol are calculated only for the adults who drink, and hidden if nobody does.
