Turning tomato into butter is not a new concept, but the hack has gained more popularity in the summer of 2025 as a way to make the most of the season's fresh bounty. Tomato butter is savory and tangy with a subtle, sweet creaminess. Just a smear of it can give your everyday toast a delicious makeover, turning it into an umami flavor bomb.
Much like using Greek yogurt in place of mayonnaise for tuna, chicken, potato, and other salads, crème fraîche provides a creamy and slightly tart alternative that's also egg free. With just the ingredients of cultured buttermilk and heavy cream, you can make your own or grab a store-bought version like Vermont Creamery Crème Fraîche. To make this swap, use about a 1:1 ratio or less, depending on your taste preferences.
