There tends to be some confusion over whether something is a fruit or a vegetable because those words actually have different meanings depending on how they are used. Botanically speaking, a fruit simply refers to the part of the plant that contains the seeds. In that sense, some things commonly thought of as vegetables (such as tomatoes) are technically fruits. However, the culinary use of the word â€œfruitâ€ specifically refers to those ingredients which have a sweet flavor when eaten raw.
So what about lemons? Are lemons fruits or vegetables?
Fortunately, the difference between the culinary and botanical definitions of fruit are irrelevant in this case, since lemons would be considered fruit by either definition of the word. Not only do they contain the seeds of the lemon tree, but they also have a flavor that could be described as sweet.
