Corn on the cob yields 28%
You buy corn on the cob by its whole weight, but you only plate 28% of it. That 72% loss is real cost the invoice never shows — here's the math.
Yield is the fraction of an ingredient that actually reaches the plate after you clean, peel, and trim it. What you pay is the AP (as-purchased) price; what it costs on the plate is the EP (edible-portion) price.
Cores, seeds, and stems are the loss; very little goes to waste here.
Say your invoice shows $0.50 per ear of corn on the cob (an example AP price).
At 28% yield, your real cost is $1.79 per ear EP — because $0.50 ÷ 0.28 = $1.79.
AP price is illustrative; the EP figure is computed (AP ÷ yield). Use your real invoice price below.Sourced: CIA Standard Yield Tables, via the Plate Cost Calculator · what yield means · edible portion
