Note to self: the Purrito’s (who is back in the states for a few days) use of the term lemon butter sauce does not and should not imply that adding lemon juice and butter to cooked pasta will result in the production of a dish with a similar flavor.
Further, the answer to what was thought to be the rhetorical question “She calls it lemon butter sauce. I don’t need to google a recipe; I’m an otherwise intelligent adult, right?” is a resounding “No.”
