Hi Vanessa! To measure out 3/4 cup of sugar or cranberries (or anything for that matter), first measure out 1/2 cup, and then 1/4 cup. If you find that you have to measure out 3/4 cup often, you might want to check a large cookware store for an expanded set of measuring cups – the large sets usually come with a 3/4 cup measure. For 3/8 teaspoon of salt, you could measure out 1/4 teaspoon, and then 1/8 teaspoon, but you probably don’t need to get that fussy. What I would do is measure out 1/4 teaspoon, then add a little bit more. Then just before the dish is done, give it a taste and see if it needs more salt--which you’d probably want to do anyway!
