It would be helpful if this recipe were written a little more clearly. The first step is to put the watermelon in the vacuum bag with the brine ingredients. However, the brine ingredients aren’t specified. Usually a recipe is written so that the ingredients are listed in the order of their use in preparation. However, in this recipe after the watermelon the tomatoes are listed and you need to look at the third step to figure out which are the brine ingredients. Furthermore, a brine is a salt solution. Either the sale for the brine was accidentally left out — assuming that the Maldon Sea Salt Flakes are used as a finishing touch as the recipe suggests — or you should change the word from brine to marindate. I am sure that the salad would taste very lovely, but the written recipe needs work.
