Not joking when I say this butter really is good on everything. It's so simple and really is a great use of summer tomatoes.
Tomato butter will keep in an airtight container for 2 weeks. Just make sure to remove from the fridge before using if you are wanting to spread it onto something like bread or a chicken.
Saving the tomato cooking oil: Do not throw this away! Tip it away into a little jar and keep it. I promise you won't regret it, it's liquid gold to use when roasting vegetables, when making a salad dressing, making a sauce. It's so good.
