I asked Auto-Hugo
Many cooks prefer to use whole canned tomatoes over chopped tomatoes because chopped tomatoes often contain added calcium chloride to maintain their shape, resulting in a less desirable texture where the tomato chunks don’t break down as well when cooking, creating a chunky sauce instead of a smooth one; whole tomatoes allow for more control over the texture by crushing them yourself as needed.
Key points about using whole tomatoes instead of chopped:
Better texture: Whole tomatoes break down more evenly when cooked, creating a smoother sauce.
Less processing: Chopped tomatoes might be more processed, potentially impacting flavor.
Calcium chloride issue: Many canned chopped tomatoes contain calcium chloride to maintain their shape, which can prevent them from fully breaking down during cooking
You live and learn, I’m usually pissed off when I accidentally pick up whole tomatoes 😂
