Choose a molcajete, blender or Cuisinart food processor for salsa

The short answer

If you want a chunky, rustic salsa with less liquid, a molcajete is the stronger choice. In a Consumer Reports comparison using the same roasted tomato, serrano and garlic salsa, the molcajete batch came out lumpier and less watery, while about 10 seconds in a blender produced a smooth, watery salsa. None of the eight tasters preferred the blended version. If you want speed and a neatly chopped raw salsa, a food processor run in short pulses is the practical middle ground. A blender suits smooth, pourable salsas, as long as you keep the blending brief.

What a molcajete is, and how it differs from other mortars and pestles

A molcajete is a Mexican mortar and pestle carved from volcanic stone, typically basalt. Its pestle is called a tejolote. So the molcajete is a type of mortar and pestle. What sets it apart from mortars made of marble, wood or ceramic is the porous volcanic stone and its traditional role in grinding salsas and other Mexican preparations.

Molcajetes are also heavy, and they need some care. The model in the Consumer Reports test held 2 cups and weighed 8 pounds. Made In recommends brushing its basalt molcajete before first use and curing it by grinding rice and salt. After that, clean it with water and a brush, never with soap or in the dishwasher, and let it dry completely before storing it. Other brands may give different instructions, so follow the ones that come with your molcajete.

Does salsa taste better from a molcajete?

In the Consumer Reports test, the tasters split evenly between the molcajete salsa and a store-bought salsa, four to four. No one chose the blender batch. The main differences tasters noticed were texture and wateriness. The blender's thin, smooth result was the clear loser, even though every batch started from the same ingredients.

There is an important caveat. The writer said they over-blended, and shorter pulses might have kept more texture. The result shows what happens when a blender runs too long on a roasted salsa. It does not show that a blender can never make good salsa. When salsa recipes disagree about which tool is better, check whether the recipes and the processing times actually match before you credit the tool.

Molcajete, blender or food processor: side-by-side

Criterion	Molcajete	Blender	Food processor (Cuisinart example)
Texture	Lumpy and irregular in the Consumer Reports test	Smooth after about 10 seconds; shorter pulses may keep more texture	Chopped, when pulsed briefly
Liquid	Less watery than the blended batch	Watery in the test	Cuisinart's recipe says to strain off excess liquid
Effort and time	Manual grinding, ingredients added in sequence; took a few minutes longer than blending	Seconds	Seconds: a short run for aromatics, then about 7 to 8 pulses
Batch size	The tested molcajete held 2 cups	Depends on the model	Cuisinart's salsa fresca makes about 1½ cups in a 7- or 9-cup processor
Handling and care	Heavy (8 pounds for the tested model); brush and water only, no soap, dry fully	Follow the manufacturer's instructions	Assemble according to the manual before running
Best fit	Roasted, rustic table salsa with a coarse texture	Smooth, pourable salsas	Fresh, chopped salsas made quickly

Blender or food processor for salsa?

Choose based on the texture you want. A blender's strength is turning ingredients smooth, which is why a short run turned a roasted salsa thin and watery. A food processor with a pulse control lets you stop at a chopped stage, so it is the better fit for chunky salsas like salsa fresca. The comparison above did not test a processor against a blender directly. Still, if a chopped texture is your goal, pulse control is the feature that matters most.

Cuisinart's salsa fresca shows the processor approach. It uses garlic, jalapeño, scallion, grape tomatoes, cilantro, lime juice and salt, and makes about 1½ cups. Use the universal blade. With the machine running, drop the garlic and jalapeño through the feed tube to chop them finely, then scrape down the bowl. Add the remaining ingredients and pulse about 7 to 8 times. Drain off any excess liquid before serving. This is a raw salsa, so its results can't be compared directly with the roasted salsa in the molcajete test.

If you use a Cuisinart FP-7 series processor, the guide says to lock the bowl clockwise, seat the universal blade on its adapter and secure the cover before running the machine. The FP-7AG has a nominal 7-cup bowl and On and Pulse/Off controls. That bowl size is the container's capacity. It is not a recommended salsa batch size.

Planning salsa for a taco night

Example: suppose you want 6 cups of salsa fresca for a taco spread. Dividing 6 cups by the 1½-cup recipe yield gives four batches. Plan on running the recipe four times rather than filling a 7-cup bowl all at once, because the bowl's nominal volume doesn't tell you how much salsa it can chop evenly. With a 2-cup molcajete, a similar amount would also take several rounds of grinding. That is why many cooks save the molcajete for a smaller batch of roasted salsa and use the processor for volume.

• Decide on texture first: coarse and irregular, chopped, or smooth.
• Set your total yield, then compare it with the recipe yield and the capacity your tool can actually handle.
• Be honest about manual work. Grinding takes a few extra minutes per batch, and a heavy stone mortar has to be lifted and cleaned.
• For a coarse roasted salsa, grind it in the molcajete. For a chopped raw salsa, pulse it briefly in a processor. For a smooth salsa, blend briefly and check often.
• When you compare flavor, hold the recipe and processing time constant so you're judging the tool and not the method.
