The 12 cup muffin pan by USA Pan. What a beauty it is. Pretty essential, I'd say. Their website says 'bake a dozen delightful concoctions in this'. Let's do that.
Measures 40 x 29 x 3.5cm. (15.75 x 11.13 x 1.38 inches).
Why USA Pan though? Since you can't feel it right now (and if you could, you'd buy it immediately) here are some of the features:
Made of aluminised steel, the choice of professionals and commercial kitchens.
Their non stick silicone, FDA approved, food-safe coating makes cleaning them super-easy.
Made in the USA
No need for paper liners and you get 'bakery-level' goodies.
"The heavy gauge steel is perfect for heat conduction, durability, and strength. The over-sized rims make it easy to transfer hot pans into and out of the oven. The ridged surface increases air circulation and resists warping so that you get consistently beautiful results."
"Whatever you make will release from the pan easily because of USA Pan's proprietary, nonstick coating: Free of PTFEs, PFOAs, and BPA; it is approved food-safe by the FDA. And it makes cleaning up simple and fast. A quick hand wash in hot water and you are good to go. Made in Pennsylvania by a family-owned business for over 50 years."
And here's the link to the mini ones (which is actually the USA Pan that first stole my heart).
