Does this sound too familiar? The chickpeas are cooked, the tahini is measured, and you're ready to blitz a fresh batch of hummus. You press go, and... nothing moves. Or the blender just keeps spinning air around a lump of almonds that refuses to cooperate.
If you want to make hummus, nut butter, or thick dips, but you’re not sure whether to do that using a KitchenAid blender or food processor, this guide is for you.
We're going to show you what each appliance does well, and which one is the better call for thick mixtures. Because using the right tool makes all the difference (and saves a lot of frustration).
Why thick mixtures behave differently in a blender
To understand why thick mixtures can be tricky in a blender, it helps to understand how a blender actually works.
Blenders create a vortex. When you turn one on, the blade spins at high speed and pulls ingredients downward and inward – toward the centre, then back up the sides of the jar. It's a continuous cycle, and it works brilliantly with liquids, soft fruit, leafy greens, and anything with enough moisture to keep moving.
The tall, narrow jar shape is part of what makes this work so well for smoothies and soups. But it's also why thick, dense ingredients behave differently. Without enough liquid to maintain that circulation, ingredients can sit above the blade rather than moving into it. The vortex stalls. Nothing blends.
This is just physics, not a flaw. A blender is engineered for fluid movement. Thick, dry mixtures like roasted nuts or drained chickpeas simply don't have the same flow.
KitchenAid blenders & thick mixtures: what's actually possible?
The Pure Power Blender
The Pure Power Blender is a brilliant everyday blender. Ten precision speeds, asymmetric blades, and a 2 litre jug with a vented lid make it excellent for smoothies, soups, sauces, and frozen ingredients.
It can also make nut butter, but it takes a hands-on approach. Our recipe uses 2 cups of nuts with a tablespoon of neutral oil, blending on low speeds with frequent stops to scrape the mixture back toward the blade. The result is smooth and creamy. It just takes more involvement than a food processor.
For hummus and thicker dips, the same principle applies: add some liquid (chickpea water or oil) and plan to stop and scrape. It's doable, but if thick mixtures are a regular part of your cooking, a food processor will be more easy and consistent.
The K400
The K400 is a different story. What sets it apart for thick mixtures is its metal base and included tamper. It's the blender we'd point you toward if you want to make nut butter in a KitchenAid blender.
The KSB4027 and KSB4028 models include a tamper (a tool that fits through the lid to push ingredients down into the blending vortex while the motor runs). With the right technique, you can make a deliciously creamy, thick mixture without being quite so hands-on.
A few things to know: you'll need at least 3 cups of nuts to give the blade enough to work with. And it takes patience. This is one task where you'll earn the result rather than set and forget.
A note on our vented lids
Both blenders have a vented lid, which means you can blend hot ingredients (something a food processor and many blenders can't safely do). Just let liquids cool slightly first and start on a low speed before building up.
Hand blenders
KitchenAid hand blenders are outstanding for what they're built for – pureeing soups straight in the pot, making quick sauces, blending dressings without a second bowl to wash. For thick, dense mixtures like hummus or nut butter, they're not the right fit. The blade geometry and motor aren't designed for that kind of sustained, heavy-load processing.
Why food processors handle thick mixtures better
Blenders work by creating movement through fluid. Food processors work differently, and that difference is exactly why they excel at thick mixtures.
A food processor uses a wide, shallow bowl. The S-blade sits low in the bowl and reaches the ingredients directly, rather than waiting for them to fall into it. Dense, dry ingredients (like chickpeas, roasted nuts or cooked lentils) stay in contact with the blade from the start. There's no vortex required. No need for liquid to keep things moving.
The motor is also built for sustained, high-resistance processing. Where a blender motor is tuned for fast, fluid movement, a food processor motor is designed to keep working through thick, heavy loads without straining.
And scraping down the sides? That's just part of the process, not a sign something's wrong. A quick scrape, a few more pulses, and you're back underway.
For thick mixtures like nut butter, the food processor is your easiest path to a smooth, creamy result. Add your roasted nuts, process in long bursts, scrape down the sides as needed, and the oils will release naturally as the nuts break down. No added liquid required.
The KitchenAid food processor range runs from a compact 3.5-cup chopper (great for small batches of pesto or dips) through to a 13-cup processor with ExactSlice™ technology for bigger batches and more versatility. There's a size for every kitchen and every appetite.

Which one is right for you?
Not sure which appliance fits your kitchen best? Here's a simple way to think about it.
Choose a KitchenAid blender if you:
-
Make smoothies, protein shakes, or blended drinks regularly
-
Often blend soups and sauces
-
Whip up pancake and crepe batters
-
Enjoy cocktails and mocktails
-
Like to drink with crushed Ice
-
Make your own mayonnaise and salad dressings
-
Want a quick, easy-to-clean tool for everyday use
-
Occasionally make nut butter
Choose a KitchenAid food processor if you:
-
Make hummus, nut butter, or thick dips on a regular basis
-
Do a lot of everyday prep (chopping, slicing, shredding, dicing, pureeing cooked fruits and vegetables)
-
Cook for a family or in bigger batches
-
Want one appliance that handles both prep work and processing
Of course, plenty of Aussie kitchens have both, and they earn their space. But if thick mixtures are a regular part of how you cook, a food processor is where you'll get the most consistent results.
Already own a KitchenAid blender? Here's how to get better results with thick mixtures
If a food processor isn't in the picture right now, there are a few things that make a real difference when blending thick mixtures.
1. Add liquid first
Even a tablespoon of oil, water, or lemon juice gives the blade something to work with. For hummus, add a splash of the chickpea cooking liquid. For nut butter, a small drizzle of neutral oil can help things along.
2. Use the tamper
If you have the K400 with tamper, use it. Lower it through the lid while the motor runs to push ingredients into the blade. Don't attempt nut butter without it.
3. Pulse rather than blend continuously
Short bursts give you more control and let you check the texture as you go. Continuous blending can overheat the motor on heavy loads.
4. Work in smaller batches
Overfilling is one of the most common reasons thick mixtures don't blend evenly. Fill the jar no more than two-thirds for best results.
5. Know when to switch
If you're stopping to scrape down the sides every few seconds, adding more and more liquid, and still not getting the result you want – a food processor may be calling your name.
The right tool makes it easy
A great blender and a great food processor are complementary. Your blender is the one for morning smoothies, silky soups, and quick sauces. Your food processor is the one for smooth hummus, nut butter made the easy way, and all the prep work that goes into a good meal.
If thick mixtures are a regular part of your cooking, a food processor will save you time, effort, and more than a few moments of wondering what went wrong.
