That’s funny because I had to look up “turn the grill on” just today in a recipe….for us grill is either the BBQ outside or a grill pan with ridges that is a stovetop thing that mimics it leaving “grill marks”. What the recipe was telling me it to put it under an overhead flame…..broil to us in the US.
Kosher salt is a medium grain “pure salt” that has no additives (no iodine added to prevent goiters in the thyroid) and is coarser than normal table salt….not so coarse that it needs to be put in a salt mill….but coarse enough that you can keep an open tin or ceramic jar of it next to the stove and gab a pinch of it to season things and see how much actually landed on the food. It was originally used by Kosher (Jewish) butchers to treat/ salt down raw chickens to draw out the blood per Kosher law. Also used to make Kosher pickles, and the perfect thing to top freshly baked soft pretzels.
You have every right to be confused by green onions. Too many similar members of the same family of onion. Green onions are also called scallions. Lowest in carbs of the onion family. Spring onions are similar but not exactly the same because they do have a small bulb at its end, and the spring onions will grow full bulbs at the end if allowed (turn into real onions) and the scallions / green onions do not. But when they are young, they are used somewhat interchangeably.
Shallots are a whole different thing and worth getting to know because they are WONDERFUL. They look like a small spring bulb covered in brown “paper” from the nursery that you are meant to plant (like a tulip bulp or narcissus). Often come as a compound bulb that you can pull apart and use in halves. They are sweeter than an onion but allas, also are higher carb than regular onions, and a good bit higher than the scallions, which are the lowest (and least sweet) of the lot. The shallots are usually used in fairly small quantities finely minced to flavor a sauce, and almost never used as an identifiable vegetable in a recipe. But they have the most lovely taste and make a great vinaigrette when minced and added to oil and vinegar. The French love them.
Arugula…same thing as rocket for you, roquette for the French. I think arugula is the Italian term, and the US has inherited the term from them.
