It is like comparing apples and oranges. Indeed oranges come into it, for the big news in the market (not the amorphous market that exerts unseen forces on our lives, but the real market with barrows and brown paper bags) is that for the first time avacados are outselling oranges (by the measure of spending).
Oranges have slumped to last place in the fruity Top 10, and avocados soared to No 8. They’re not in the big time with the three perennial favourites, apples, grapes and bananas, which would be like Joe Dolce’s Shaddap You Face keeping Ultravox’s Vienna from No 1, but it’s good going for a fruit hard to find ripe without being horrid inside.
But is an avocado a fruit? Of course, botanically, but in a tart tart or a fruit fool, rhubarb is fruitier. These category errors are more slippery than the philosopher Gilbert Ryle gave credit.
