Leafy greens like spinach, parsley and kale can bog down poor-performing blenders. For example, the entry-level Braun PureMix never made it past our spinach-based pesto recipe. The Omega OM7560 had trouble too.
It couldn't create a properly blended pesto in the 15 pulses or less we like to see. It got there in the long run, but I had to periodically push spinach leaves down further into the jar. I had the same experience with the KitchenAid Pro Line Series. The Vitamix 7500, Vitamix Ascent 3500 ($600 at Amazon) and Blendtec Designer Series Wildside all passed our pesto trial without any special assistance.
Turning heavy cream into a fluffy dessert topping wasn't difficult with the Omega. The blender successfully accomplished the task after nine blade pulses at high speed. A capable blender does the job in 10 to 15 pulses.
Churning dry raw almonds into a creamy and spreadable paste is our toughest blender challenge. Making almond butter is not this blender's forte. First, the Omega crushed almonds into nut flour in 10 pulses. That's relatively few compared with the 30 pulses the KitchenAid Pro Line Series required. The budget Braun PureMix completed the task in 12 pulses, though its texture was very inconsistent.
But to create nut butter, I had to push the appliance to the limit. It took an hour of blending (along with healthy doses of manually mixing) to make almond butter. The blender's temperature sensor wasn't too happy, either: Toward the end of the hour, it shut down the blender's motor multiple times until it had time to cool. There's no special light or indicator to warn you of an overheat either. The blender simply quits.
The Blendtec Wildside, KitchenAid Pro Line Series and Vitamix 7500 completed this grueling challenge in under 8 minutes.
One torture test we inflict upon blenders involves letting them do their worst to an 8-ounce block of cold cheddar cheese. It's not as physically demanding as our nut butter trial. And sure, it's unlikely that regular blender owners would do this. Still, not many machines achieve acceptable results. For instance the Braun PureMix couldn't properly wrap its blades around our cheddar block. They spun freely while most of the cheese remained intact.
Surprisingly the Omega successfully shredded its sample block of cheese. It did take some outside help. I needed to give the blender jar a couple of shakes so the blades could grab hold and finish the job.
The Omega managed to mix a smooth batter. Still, I had to deviate from the recommended recipe (on a supermarket mix) and add slightly more water. If I didn't, or if I ran the blender too fast, the mixture thickened and almost became dough.
Unlike many other models from KitchenAid, Vitamix and Blendtec, the Omega doesn't have a special cleaning mode. Even so, the Omega machine is easy to clean and wash by hand. That's especially true if you first run it with some warm water and a few drops of dish detergent in the jar. Be advised that the blender's jar (including its blade assembly) is not dishwasher safe.
Skip this blender for something better
At nearly $500, the Omega's flaws are hard to forgive. It lacks the capabilities and features of other premium blenders. If you're going to spend this much, choose something else. I suggest either the $300or $480 .
Both appliances can blend up a storm, especially when you compare it to the Omega. Blendtec's Designer Series comes with loads of preset functions that will let you whip up smoothies, frozen drinks and other items with a single button press. We don't know how long this price will last, but $300 seems like a steal. The Vitamix 7500's combination of performance and alluring recipe book are compelling, especially when discounted to $480.
