"Making parsley turn in boxes or “the putting green” as it is commonly referred to as is time consuming to say the least. First you have to find parsley no easy task sometimes. You need to find parsley that is all the same shade of green – and that looks alike. You may decide to do a combo lettuce and parsley box or straight up lettuce the choice is yours! I personally do parsley boxes 100% of the time. Our team is small – just my husband and I and the occasional friend that shows up. This task always falls on my lap. I have had many a night where myself and a few friends have had parsley parties working on the 4 turn in boxes for an hour or more. . However I have begun to get into the habit of doing them at home prior to a contest and transferring them on site. I first saw a version of this on the Pickled Pig Forum. This is how I do it.
Start with 4 turn in boxes and label them for each category – depending on how you present your food you may want a box that is fuller and or lower in height with the parsley.
Wash and rinse your parsley thoroughly. Parsley is grown in super moist soil and it can be very gritty when you purchase it.
For 4 boxes I will use anywhere from 12- 18 heads of parsley depending on the size and quality. If you are attending a contest with friends consider splitting the cost of a case. I place my parsley in a bin with a couple inches of water at the bottom to keep it moist and hydrated. IF you are keeping the parsley in your fridge for a couple of days make sure to change out the water."
