Preheat the oven to 450°F (232°C). Generously grease 12 muffin cups with oil.

Boil water in a large saucepan with safflower oil and salt over medium heat until it reaches a rolling boil.

Add the matzo cake meal all at once, stirring quickly until blended. Remove from heat and let stand for 5 minutes.

Pour the mixture into a blender, add 2 eggs, and blend until smooth, then continue adding the remaining eggs one by one.

Fill the prepared muffin cups three-fourths full with the batter.

Bake for 18-22 minutes until puffed up and golden brown. Let sit in the oven for 10 minutes after baking.

Transfer popovers to a wire rack to cool slightly. Serve warm.
