Softened butteris what we call for in our classicGrilled Cheese Sandwich.

So is butter your only optionor even your best bet?

Fat chance, saysSarah Brekke, M.S.,Better Homes & GardensTest Kitchen brand manager.

If you go with salted butter, youll layer on even more flavor.

Mayonnaise is spreadable right out of the container, no softening or whipping required.

And if you opt for kewpie mayonnaise, your coating will come with a subtle kick of savory flavor.

Plus, ghee doesnt need to be refrigerated.

Even when chilled, the texture is more spreadable than cold butter.

(Olive oiland avocado are two popularpantry stapleoptions for grilled cheese.)

You will sacrifice a bit of that rich, buttery, fatty flavor in the end though."

The majority called out mayonnaise for the ease of use and even browning," Brekke says.

Still, butter was the clear winner for that classic grilled cheese flavor even though its a tad fussier.

Just be sure not to skip the fat all together.

The fat provides richnessandallows the bread to toast on the exterior while staying nicely soft and tender underneath.
