This is so true. My dad is a keen gardener and grows like, a dozen? Different fruits. When the figs are ripe they’re my favourite. When the grapes are ripe, the muscatels are my favourite (the red seedless are pretty good but can’t hold a candle to them). Loquats, in a good year, are my favourite fruit. Likewise plums, raspberries, and mandarins. Genuinely I think my favourite fruit is whatever’s good (and that I like) right now.
