Is Homemade Tahini Worth Making? A Cost Breakdown
Tahini — that creamy, nutty paste made from ground sesame seeds — is a staple in hummus, salad dressings, noodle sauces, and grain bowls. But a single jar from premium brands like Soom can run $10–$14 for 16 oz, and even Whole Foods 365 or generic store brands hover around $6–$9. If you use tahini often, the cost adds up fast.
The good news: tahini is one of the simplest nut-and-seed butters to make at home. You need sesame seeds, a splash of neutral oil (or none at all for a thicker paste), and a food processor. The question is whether your grocery store's bulk-bin sesame price makes it cheaper than pulling a jar off the shelf.
Raw vs. Toasted Sesame Seeds
Most commercial tahini uses hulled, lightly toasted sesame seeds, which produce a pale, mild paste. Raw sesame seeds yield a slightly more bitter, earthier tahini. Toasted seeds deepen the flavor considerably. Either way, the seed cost dominates the math.
What Drives the Cost
A single cup of tahini requires roughly 8 oz (half a pound) of sesame seeds. Bulk sesame seeds at natural grocery stores typically run $3–$6 per pound, putting your seed cost at $1.50–$3.00 per cup. Add a teaspoon or two of neutral oil and a tiny sliver of electricity, and the total homemade cost per cup is usually $2–$4 — often well below what premium jars cost at retail.
Frequently Asked Questions
How many ounces of sesame seeds do I need for one cup of tahini?
Generally about 8 oz (half a pound) of sesame seeds will yield close to 1 cup of tahini. The seeds lose very little mass during grinding, but the paste is denser than the seeds by volume.
Should I use hulled or unhulled sesame seeds?
Most commercial tahini uses hulled sesame seeds, which produce a creamier, milder paste. Unhulled seeds are more nutritious but yield a darker, slightly more bitter tahini. Hulled is generally easier to find in bulk and closer to what you'd buy in a store jar.
Do I need to add oil to homemade tahini?
Not always. A high-powered food processor can break the seeds down into a pourable paste without added oil, especially if you run it for several minutes. A small drizzle of neutral oil helps with texture and makes the paste silkier.
How does homemade tahini compare to brands like Soom or Whole Foods 365?
Soom runs $12–$14 for 16 oz, putting its per-cup cost around $6–$7. Whole Foods 365 and generic brands are typically $6–$9 for 16 oz, or $3–$4.50 per cup. If your bulk sesame seeds cost under $5 per pound, homemade will almost always beat both on price per cup.
How long does homemade tahini last?
Stored in an airtight jar in the refrigerator, homemade tahini keeps for 4–6 weeks. In the pantry it can last 2–4 weeks. Give it a stir before each use — separation is normal.
