You’re standing in the grocery aisle, staring at a $9 jar of sesame paste that looks like a layer of concrete topped with a puddle of oil. We’ve all been there. It’s frustrating. You buy it anyway because you want that creamy hummus or that drizzly lemon-tahini dressing, but the moment you get home and try to stir it, the oil splashes onto your counter and the sludge at the bottom refuses to budge. Honestly, learning how to make tahini paste at home is less about saving money—though you definitely will—and more about escaping the tyranny of the chalky, bitter store-bought stuff.
Making it yourself is dead simple. It's basically just seeds and a little bit of patience. But there is a massive difference between "okay" tahini and the kind of liquid gold they serve in places like Tel Aviv or Amman.
The secret isn't some fancy equipment. It’s the heat. And the salt. Most people skip the toast or they over-toast, and that's where the bitterness comes from. If you’ve ever wondered why your homemade version tastes like burnt rubber, you probably left the seeds in the pan for thirty seconds too long.
Why Fresh Sesame Matters More Than You Think
Most commercial tahini sits on a shelf for months. Sesame seeds are packed with oils that go rancid. When those oils oxidize, they get sharp and unpleasantly metallic. When you learn how to make tahini paste in your own kitchen, you’re using fresh seeds and eating them while the fats are still stable and sweet.
There are two main types of sesame seeds: hulled and unhulled. Unhulled seeds have the bran intact. They’re darker, crunchier, and significantly more bitter. They also have more calcium, but if we’re talking about flavor and that silk-sheet texture, you want hulled seeds. They’re white or off-white. Use those. If you use the black ones, you’ll get something that looks like engine oil and tastes like a forest fire. It has its place, but not in your morning smoothie.
The Toasting Trap
Let's talk about the stove. Some people swear by raw tahini. They say it's "cleaner." I think it tastes like wet cardboard. Toasting the seeds is non-negotiable for flavor.

Get a wide skillet. Don't add oil. Throw the seeds in and keep them moving. This is the part where you can't walk away to check your phone. Sesame seeds are tiny; they go from "pale" to "charred" in the blink of an eye. You're looking for a very light golden hue and a smell that reminds you of popcorn. As soon as you smell that nuttiness, pull them off the heat. Immediately. Even the residual heat of the pan can overcook them if they just sit there.
Transfer them to a plate to cool. If you put hot seeds into a blender, the steam will mess with the oil emulsification. You’ll end up with a clumpy mess instead of a smooth pour.
The Equipment: Blender vs. Food Processor
You need power. There’s no way around it. A mortar and pestle is traditional, and if you want to spend forty minutes working on your forearms, go for it. It produces a rustic, slightly gritty paste that’s actually quite nice on toast.
But for the creamy stuff? Use a high-speed blender like a Vitamix or a decent food processor.
Blenders are actually better for small batches because the blades are positioned lower. Food processors sometimes just fling the seeds against the walls and you spend half your time scraping them down with a spatula. It's annoying. If you're making a big batch—say, two or three cups of seeds—the food processor handles the volume better.

The Oil Question
Purists will tell you that you don't need oil. Technically, they're right. Sesame seeds are about 50% fat. If you grind them long enough, they will eventually turn into a paste.
However.
Unless you have an industrial-grade stone mill, your homemade tahini will likely be a bit thick. Adding a neutral oil—like grapeseed, avocado, or a very light olive oil—helps the blades catch and creates that drizzlable consistency. Don't use toasted sesame oil. It’s too strong. It’ll overwhelm the delicate sweetness of the seeds. You’re looking for a supporting actor, not a lead.
Step-by-Step: How to Make Tahini Paste
- Measure out two cups of hulled sesame seeds. This makes a decent-sized jar that will last you a month in the fridge.
- Toast them. Medium-low heat. Shake the pan. Five minutes, tops. Look for the color of light sand.
- Cool them down. Spread them out. Don't be impatient.
- Dump them into the processor. Start pulsing. It’ll look like sand at first. Then it’ll look like thick almond flour.
- Keep going. This is where people quit. They see the thick paste and think that's it. No. Keep processing for a full 3 to 5 minutes.
- Stream in the oil. Add one tablespoon at a time. Usually, 2 to 4 tablespoons is the sweet spot for two cups of seeds.
- The Salt. A pinch of fine sea salt changes everything. It cuts the bitterness and wakes up the nuttiness.
Common Mistakes That Ruin the Batch
Water is the enemy.
If you get a single drop of water in your blender while you’re making tahini, the whole thing will seize. It turns into a stiff, clay-like ball instantly. This is because of the way the proteins and fats interact. Make sure your equipment is bone-dry. If you're washing your herbs for hummus nearby, be careful.

Another big one: over-salting. Tahini is often used as an ingredient in other things that are already salty (like soy sauce dressings or salted chickpeas). Keep the salt in the paste minimal. You can always add more to the final dish, but you can't take it out of the jar.
Storage Reality
Homemade tahini doesn't have the stabilizers that the stuff from the store has. It will separate. That’s normal. The oil will rise to the top, and the solids will settle.
Store it in a glass jar. Plastic tends to absorb the smell of the oil over time, and it can get funky. In the fridge, it'll stay good for about a month. If it starts to smell like old crayons, it’s gone rancid. Toss it.
Beyond Hummus: What to Do With Your Creation
Now that you know how to make tahini paste, don't just let it sit there.
- Tahini and Honey: This is the Mediterranean version of peanut butter and jelly. Spread it on sourdough, drizzle with honey, and add a sprinkle of flaky salt. It's incredible.
- The "Magic" Sauce: Whisk your tahini with lemon juice, a smashed garlic clove, and a splash of ice-cold water. Magic happens here—the sauce will turn white and thicken up like mayonnaise. It’s the perfect dressing for roasted cauliflower or grilled chicken.
- Baking: You can swap tahini for nut butters in cookie recipes. It adds a sophisticated, slightly savory depth to chocolate chip cookies.
There's a reason chefs like Michael Solomonov and Yotam Ottolenghi obsess over the quality of their tahini. It is the backbone of so many flavors. When you make it yourself, you control the roast, the salt, and the texture. You're not just making an ingredient; you're making a staple that's actually worth the shelf space.
Actionable Steps for the Perfect Batch
- Buy fresh seeds: Check the "bulk" bins at a local Mediterranean or Middle Eastern grocer. They have a higher turnover than the tiny, expensive glass spice jars at the supermarket.
- The "Spoon Test": After blending, dip a spoon in. The tahini should coat the back of the spoon but still run off in a continuous, silk-like ribbon. If it falls in clumps, add half a tablespoon more oil and blend for another minute.
- Temperature check: If the paste feels hot to the touch from the friction of the blades, stop. Let it cool for ten minutes before finishing. Overheating the oil during blending can encourage rancidity.
- Wait for the "Bloom": After you bottle it, let it sit for a few hours. The flavors meld, and the texture sets slightly. It actually tastes better on day two.
The transition from store-bought to homemade is a one-way street. Once you taste the difference between the bitter, shelf-stable jars and the sweet, nutty cream you've made in your own kitchen, you won't go back. Grab a bag of seeds and start toasting. It’s the single easiest way to level up your cooking this week.
