why they should make powdered lemon

i want to make vegan mac and cheese. i've been craving it for a bit over a week now... the main ingedient, which i only have in the house if i'm making vegan mac and cheese is cashews. so i bought cashews... the only thing i'm missing now is lemon juice. and darn it all to heck. if they made lemon juice powder, i would deifnitely have osme sitting around the house... but they don't, so i don't and while my belly grumbles with a hankering for vegan mac and cheese i can offer it nothing. except raw cashews and, while tasty, are being saved for the darned mac and cheese. do you feel my pain??
