At the end of the day, both are just tomatoes that had a rough life. One got chopped up by a really sharp knife, and the other got gently smashed by a friendly giant. They both come from the same red, vine-ripened destiny. But they act differently in the kitchen.
So next time you’re in the grocery store aisle, ask yourself: “Do I want a party with individual guests, or do I want a dance floor where everyone is already melded together?” That’s the difference. Diced are for structure. Crushed are for soul. And your pasta will thank you for knowing the difference.
Now go forth and cook. And for crying out loud, don’t use diced tomatoes for the lasagna. Your nonna is watching from heaven, and she is disappointed.
