Awww yissss, made Nagi's tuna mornay (https://www.recipetineats.com/tuna-mornay-casserole-pasta-bake/) with the sixteen year-old and it was GOOOOOOOOD.
I really need to look up how to make white sauce without it taking an eternity though, because jesus christ it was seriously half an hour of non-stop stirring and we ended up cheating and putting corn starch in anyway.
