My tradition every holiday season (and at any other time of the year) is to make a food gift. I love your muesli and have made it many times. Can you explain how to make this in quantity–can I double the recipe?

A well-loved food gift of mine is a crunchy mixture that includes rolled oats and various other flaky things and seeds, and muesli, my favorite way is at the top of the list. The basic recipes yields six cups. It contains rolled oats, rolled spelt flakes, rolled wheat flakes, pumpkin seeds, cashews, and sunflower seeds. A honey and oil mixture gets poured over the collection of goodies, and it all gets spooned onto and scattered on a baking pan. At some point during the process, wide-flake coconut is incorporated and tossed about, then the whole concoction is baked until everything is golden. Cooled and crumbled, the muesli is light but sturdy. The core recipe can be doubled successfully, keeping the following suggestions in mind: Use 1 cup plus 1 tablespoon honey, 1/2 cup plain vegetable oil, and 4 teaspoons vanilla extract; divide the mixture between 2 large rimmed sheet pans (each pan measuring 13 by 18 inches), each lined with a sheet of ovenproof kitchen parchment paper and filmed with nonstick oil spray; bake the sheet pans of muesli on the upper and lower third level oven racks, exchanging the pans from top to bottom and bottom to top halfway through baking; and store the mixture in 1-quart jars with tight-fitting lids.
