How to Use Yeast, Baking Soda, and Baking Powder

Baked goods generally rely on a chemical leavener, baking soda, baking powder, or yeast for lift.

Without some sort of leavener, most baked goods would be very dense and very flat.

Baking Soda

Baking Soda

Baking soda, also known as bicarbonate of soda, is an ALKALI used as a leavener in baked goods.

When combined with an acid ingredient such as buttermilk, yogurt, or molasses, baking soda produces carbon dioxide gas bubbles, thereby, causing a dough or batter to rise.

It also neutralizes acidity and produces tender baked goods.

Because it reacts immediately when moistened, it should always be mixed with the other dry ingredients before adding any liquid.

The resulting batter should be placed in the oven immediately.

At one time, baking soda was used in the cooking water of green vegetables to preserve their color. That practice was discontinued, however, when it was discovered that baking soda destroys vitamin C content in vegetables.

To determine if your baking soda is still worth using, combine ¼ teaspoon with 2 teaspoons of vinegar, if it bubbles the soda is still good.

Never dip a wet measuring spoon into baking soda, moisture activates the soda.

Place an opened box of baking soda on a refrigerator shelf to keep the fridge smelling fresh.

Change every three months.

To help clean pans with baked-on foods, sprinkle with baking soda, add a little hot water and allow them to sit overnight. The next day, it will be easier to clean.

Baking powder

Baking powder is used to make light, fluffy texture in cakes and baked goods.

Before baking powder was invented, whipped egg whites or yeast were used, some recipes rely on these today.

Baking powder is a leavener containing a combination of baking soda, an acid (such as cream of tartar), and something to absorb moisture (such as cornstarch).

When mixed with liquid, baking powder releases carbon dioxide gas bubbles that cause a bread or cake to rise.

There are three basic kinds of baking powder. The most common is “double-acting,”(which is most supermarket brands) which releases some gas when it becomes wet and the rest when exposed to oven heat.

“Single -acting tartrate” and “phosphate baking powders (hard to find in most American supermarkets) release their gases as soon as they are moistened.

This type of powder does not provide sufficient leavening for dough with little liquid, such as muffins or scones.


Always check the date on the bottom of the baking-powder can before purchase.

To test and see if the powder is still active combine 1 teaspoon with 1/3 cup of hot water.

If it really bubbles, it is OK.

Because it is perishable, baking powder should be kept in a cool, dry place.

Since moisture causes deterioration, never dip a wet measuring spoon into the baking-powder can.

Because baking powder contains baking soda, when liquid is added, they react, producing a carbon dioxide gas.

If you use baking soda on its own, your need to add an acidic ingredient such as lemon juice or buttermilk.


Cake yeast

Stonewall Kitchen, LLC

Cake yeast, fresh yeast, or compressed yeast is stocked in the refrigerator section of the supermarket.

This type of yeast, sold as little cubes, is reliably active, but very perishable.

It is mostly used by commercial bakers, not by us  – home cooks.

Active Dry Yeast

Sold in packets or jars, active dry yeast is called for in most bread recipes.

When using active dry yeast, the granules must first be proofed, or dissolved in liquid, with some sugar to speed up the process.

This is because, when the yeast was packaged, it was given a heat treatment that killed the outermost cells.

Proofing sloughs off the dead cells and renders the yeast active.

Helpful hint using yeast substitutions

And you must proof the yeast too. Dissolve it in a portion of the water called for in the recipe, heated to a perfect 105ºF.

Instant (Rapid-Rise) Yeast

Much like active dry yeast, HOWEVER, it has undergone a gentler drying process that has not destroyed the outer cells.

Instant yeast does NOT require proofing and can be added directly to the dry ingredients when making bread.

It is called INSTANT yeast.

When baking basic bread, such as baguettes, that contain just flour, salt, water, and yeast, the instant yeast yields a cleaner, purer flavor than active dry yeast because it does not contain any dead yeast cells.

However, in bread that contains butter, sugar, and other flavorings, there should be no concern for flavor changes.

Storing yeast and leaveners

Keep baking powder and baking soda in the pantry, away from any direct sunlight.

Expert testers say baking powder’s potency significantly deteriorates after just 6-months.

Yeast can be stored in the refrigerator or freezer to slow deterioration.

And because yeast is a living organism, adhere to expiration dates.

To make the cake

  • Preheat oven to 350ºF

  • In a large bowl combine the eggs, sugar, pumpkin, and oil. Mix until smooth.
  • In a separate bowl combine the flour, baking powder, cinnamon, baking soda, salt, cloves, ginger, and nutmeg. Using a large whisk, mix these ingredients thoroughly until all large lumps disappear.
  • Add flour mixture to the liquid ingredients. Stir until thoroughly combined and all the white color from the flour is gone.
  • Spread evenly in the prepared baking dish.
  • Cook for approximately 30-35 minutes. Test cake doneness with a toothpick entered into the center of the cake. When removed, if the toothpick is clean, the cake is done.
  • Allow the cake to cool completely before frosting.

To make the frosting

  • In a stand mixture, or use a hand-held mixture, beat the butter for about 30 seconds.
  • Add half the confectioner's sugar, half the rum, and the vanilla extract to the butter. Beat with the mixture until combined.
  • Add the remainder of sugar and rum. Beat the frosting until smooth.
  • Scrape down the sides of the bowl. Beat the frosting 20 more seconds.
  • Spread evenly over the cooled pumpkin cake. For best results, store the cake in the refrigerator for 2 hours, up to overnight before serving.
  • Remove from the refrigerator about one hour before serving.
  • Cake will keep for 4-5 days, in the refrigerator, stored in an airtight container.
