We specifically talked about Granny Smiths.

我明确说要澳大利亚绿苹果的。

The first thing we're going to do is prep some granny smith apples.

我们要做的第一件事是准备一些澳洲青苹果。

The granny smiths are the green ones, they're also the most tart of the apple family.

格兰尼史密斯是绿色的，他们也是苹果家族中最酸的。

They would have a hard time differentiating between the colors of red and green, making it difficult to find a Red Delicious apple in a field of Granny Smiths.

他们很难区分红色和绿色的颜色，因此很难在青苹果田里找到红美味苹果。
