What iS the measurement / quantity for lemons in farro salad with mushrooms? It says 2 lemon juice but does not specify the measurement.
Not the recipe writer but I'd suggest it's to taste, based on "2 lemons, juiced" - 1/4 cup of lemon juice can have different sweet/sour qualities depending on the lemon itself, so just add it till it tastes good :)
Take 2 medium lemons and juice 'em. Then add results to recipe. Don't sweat the small stuff worse case it's slightly lemony
