IMAGINE COFFEE tomorrow morning accompanied by the steamy fragrance of a home-baked muffin, just begging for butter.

There's a sub-genus of the bread world that is faster than a speeding bullet from oven to tummy and it doesnT come in a box. Welcome quick breads to your breakfast repertoire.

Short preparation and baking time, usually under 30 minutes, means you can mix your ingredients in five minutes and spend the rest of the time taking a shower, getting dressed or attending to whatever morning duties are peculiar to your household. The warm scent of breakfast bread is also an effective family alarm clock.

Quick breads take the form of muffins, biscuits and breads that rely on the baking powder for their leavening. The rise and fall of the yeast empire takes more time than most of us have in the morning and thus is relegated to less active days.

Many quick breads are close cousins by way of batter. Here are basic ingredients and mixing methods that lend themselves to whatever additions you and your family prefer, including nuts, fruits and spices. Health fans can incorporate whole grains and seeds with the bonus of additive-free baking.

To make your quick breads even quicker, it's a good idea to set out utensils, recipe and nonrefrigerated ingredients the night before. The dry ingredients can be mixed together the night before, too.

Leftover quick breads should be stored well wrapped in plastic or foil. Most can be reheated successfully at 375 degrees for 10 minutes with a dab of butter on the surface if you fear they might dry out on the second go-round.

With commercially prepared muffins going at $1 for six and coffee cakes verging on $2, quick breads will prove more economical. They also go well in lunch boxes, as after-school snacks and for midnight forays in the kitchen.
