how to know which guavas have a pink inside?

To determine if a guava has a pink inside, look for varieties known for their pink flesh, such as the 'Pink Guava' or 'Strawberry Guava.' The skin color can be a hint; pink-fleshed guavas often have yellow or light green skin. Additionally, ripe guavas typically yield slightly to gentle pressure and emit a sweet aroma. If possible, check with the seller about the variety to ensure you're selecting one with pink flesh.
