-
Preheat the oven to 375°F. Lightly grease (or line with parchment) two baking sheets.
-
In a large bowl, combine the sugars, butter, shortening, salt, vanilla and almond extracts, vinegar, and baking soda, beating until smooth and creamy.
-
Beat in the egg, again beating until smooth. Scrape the bottom and sides of the bowl with a spatula to make sure everything is thoroughly combined.
-
Mix in the flour, then the chips.
-
Use a spoon (or a tablespoon cookie scoop) to scoop 1 1/4" balls of dough onto the prepared baking sheets, leaving 2" between them on all sides; they'll spread.
-
For enticing salty-sweet flavor, sprinkle a touch of sea salt atop the cookies before putting them in the oven, if desired.
-
Bake the cookies for 11 to 12 minutes, until their edges are chestnut brown and their tops are light golden brown, almost blonde.
-
Remove the cookies from the oven, and cool on the pan until they've set enough to move without breaking. Repeat with the remaining dough.
-
Store cookies, well wrapped, at room temperature for up to 5 days; freeze for longer storage.
