If you peel and slice ginger and spread it out on a baking tray and freeze it like that, you can just bag it up for the freezer and use slices as an when you need them for cooking. The slices don't stick together, either. There is always a bag of that in my freezer and bags of whole chillies, because they slice straight from frozen. Lemon grass stalks are good to freeze, too, a quick bash when they come out of the freezer and chuck them in the pan. Easy peasy.
I reckon garlic could be sliced up and frozen like I do with ginger, but garlic never gets the chance to go off in my house.
As for recent discoveries, I am very taken with Sainbury's own brand cartons of tomatoes with added olives. I only got one because I thought it would be useful for a quick add in when I was making a sauce but it is lovely as it is with spaghetti.
