 It's not just online recipes that give false and misleading times. Items packaged for retail sales also give misleading "ready-to-eat" times.

 My understanding is that both Munroe and R. Author share a reference frame in which the kitchen which the R. Author observed to write his post was moving at relativistic speed. This would explain why, when Munroe (foolishly) prepares the dish in the same reference frame where he lives, it takes longer. My issue is with the onion dimension calculation here: length contraction means that R. Author observes onions to be longitudinally shorter than they "really" are, by a factor gamma=3. Then, if we *let Munroe cook* in his own reference frame, he will need to cut onions longitudinally (this requires knowing the direction of motion of the kitchen) longer by gamma, so 3/4", in order to replicate the kitchen's work. Note that he should still cut the onion to 1/4" in the transverse directions, which experience no length contraction. --[[User:Henrynester|Henrynester]] ([[User talk:Henrynester|talk]]) 15:34, 25 April 2023 (UTC)

	The first non-sponsored Google hit on cooking black beans says, "Cook soaked beans for about 45 to 60 minutes and unsoaked for about 50 to 65 minutes." However, my half-used 32 oz. bag of "Great Value" (Walmart) black beans says a "quick soak" takes an hour after a two minute boil, and then cooking soaked beans requires additional simmering for "1 - 1/2 to 2 hours". Can we agree that given the title and estimated time of the recipe, it almost certainly assumed the use of canned beans, but Randall had only dried beans?
