If you REALLY REALLY like the smoothies then you've got to have more ice cube trays.
Me, I got 9 of them!
Rubbermaid – White Ice Cube Tray – The cheapos that work well – pack of 4 trays
OXO Good Grips Covered Ice Cube Tray – Slightly higher end trays with a cover/a little easier to remove long term. You can utilize this for freezing the leftover pumpkins and/or coconut cream for the smoothies too.
Mumi&Bubi Solids Starter Kit – Large Bulk Style Ice Cube Trays – (holds 21 ice cubes instead of 14)
