Great flavor, but I wouldn't try to make into cut out cookies.
Fat composition dictates the final texture of baked goods, and combining margarine with vegetable oil yields a dough that spreads differently than standard all-butter variations. Liquid oil interferes with gluten development by coating the flour proteins, producing a remarkably soft interior crumb while the margarine provides necessary water content for steam production during the bake. Sifting the four cups of all-purpose flour with one teaspoon of cream of tartar and baking soda ensures an even distribution of leavening agents, preventing dense pockets in the final rounds.
Chilling this dough for a mandatory minimum of two hours solidifies the fats, which directly controls the rate at which the cookies flatten in the 350 degree oven. Working in batches keeps the remaining unbaked portions firm in the refrigerator; warm dough leads to excessive spreading and greasy edges. Portioning exact tablespoon-sized amounts ensures uniform thermal absorption, allowing the edges to turn light brown around the ten to twelve minute mark while the centers remain soft and pale.
Leftover baked cookies maintain optimal texture for up to five days when stored in an airtight container at room temperature with a slice of plain white bread to regulate ambient moisture. Storing them this way prevents the starches from retrograding too quickly, which is the primary cause of staleness in high-sugar baked goods. If freezing unbaked portions, shape the dough balls before cold storage and bake straight from frozen by adding two extra minutes to the timer.
Adapting this formula for dietary preferences requires careful ingredient selection without altering the structural chemistry of the fat and flour ratio. Substituting standard margarine with a plant-based block alternative containing at least eighty percent fat maintains the correct moisture levels needed for the chemical leaveners to react properly with the cream of tartar.
