If you have access to freshly brewed espresso, you may wish to use it in the liquid form, rather than using instant espresso. For recipes that call for instant espresso reconstituted with water, simply substitute the same amount of fresh espresso. You can control the strength of the espresso if you are brewing it yourself, and adjust according to taste. However, if the recipe calls for instant espresso reconstituted in a ratio of less water to powder than typically used to make the beverage if you were simply drinking it, you need to brew your espresso significantly stronger for a one-to-one substitution, or add more espresso and adjust the dry ingredients to reflect this addition.

If your recipe calls for brewed espresso, but you want to increase the intensity of the espresso flavor, use instant espresso, instead. Because you reconstitute the instant espresso with water, you can use the same amount of liquid, but add a larger amount of the espresso granules, thereby making a significantly stronger brew. Alternatively, try using the called for amount of espresso and adding additional instant espresso powder directly into the batter or dough. The instant espresso dissolves in the moisture of the batter without changing the ratio of wet to dry ingredients.

If you decide to modify a recipe to include espresso, you must consider whether the batter or dough can handle extra liquid and how you will balance it out with the other ingredients. For a light espresso flavor, you may be able to add a small amount of freshly brewed espresso and balance it out with a slightly higher amount of flour, resulting in a slightly moister baked good. However, to achieve a strong espresso flavor, consider using instant espresso mixed with only a tablespoon or two of water, in place of extracts. Or, for recipes such as cookie dough, add the instant espresso granules directly to the batter and mix well.

For many recipes, such as cookie dough and some cakes, eggs are used not only as stabilizers and emulsifiers, but also to add moisture. To this end, if you desire to use freshly brewed espresso, rather than powder, reduce the number of eggs included in the batter or dough and add in espresso, with a little extra baking soda or powder. If you don't have instant espresso on hand for a recipe that calls for it, but do have espresso beans for brewing, you can create your own espresso granules. Instant espresso is made from already-brewed espresso grounds that are then dried and ground further, into a very fine powder. Take the leftover grounds from your morning espresso, dry them, and use a mortar and pestle to grind them further.
