They have awesome ice cube trays with lids, which are 2oz or 4oz each service (depending on which you buy). I have 2 of them and if I make more than that I but it in normal ice cube trays (mine are ~1oz each) and but the tray in a freezer bag (to keep it safe and clean). Then once they are completely frozen (usually a day or 2 because I forget) I take the "cubes" out and put them in an labeled, dated freezer bag so I can reuse the trays. This works really well and doesn't require tons of containers. Then I put the cubes in my lidded serving dish the day I want to use them or the night before and a quick warm up in the microwave is all they need.
