xixi, as for fresh vs. froze, don't worry too much.
If you can get your hands on fresh ones in store, go for them, otherwise, there is nothing wrong using frozen fruit sometimes. Being frozen does not necessarily mean the fruit/veggie are not fresh anymore, for example, good quality frozen blueberries are usually frozen right after picking, they are even fresher than the ones shipped to store days later. The same thing applies to long string beans, etc.
等外面雨停了,我就去买冷冻水果去,我也不知道怎么了,着魔一样,就想做桃子
我还要做蓝莓,上次问儿医,她居然说不知道怎么喂baby蓝莓......
