Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to adjust a cookie recipe for high altitude [title] Do not over-beat your eggs. [step] This will add too much air to the cookies. With high altitude baking, the low air pressure causes the air bubbles to expand faster.

Ending1: The cookies will rise quickly and then collapse, making them dry and brittle. [substeps] If your cookie recipe calls for egg whites, only beat them to a soft-peak. Ending2: Adding too much air is better for churning or removing the air bubbles than a rotten egg. Limit the baking time to 1-3 hours. Ending3: Anything higher risks spoiling the recipe by causing rising bubbles, which will result in soggy cookies. [title] Increase the slope of the cookie dough. Ending4: If this happens, the eggs will overcook quicker. You want to plan ahead or your cookies won't turn out just right.
