I talked about tomatoes back in 2018 in this post. Today, I came across these for the first time. The Chinese describes them as 绿色千禧小番茄 (lǜ sè qiān xǐ xiǎo fān qié) which translates as 'green jubilee small tomatoes'. I call them 'green cherry tomatoes'.
To my amusement they come with instructions! Because China thinks of cherry tomatoes as a table fruit and many use them in fruit salads, they have to be advised to stir fry these until they burst and use as a quick sauce with noodles as a sweet and sour sauce or, as it's known in Chinese, a 'sour and sweet sauce'.
