Is Homemade Tahini Actually Cheaper?
Tahini — the silky sesame seed paste used in hummus, dressings, and baked goods — can run $8 to $14 per jar at the grocery store, especially for quality brands like Soom, Artisana, or Seed + Mill. Making it at home sounds appealing, but sesame seeds are not exactly cheap either. The real answer depends entirely on where you buy your seeds and how much oil you add.
A standard batch of homemade tahini uses about one pound (16 oz) of sesame seeds plus a small amount of neutral oil such as avocado or light olive oil. The seeds are typically toasted briefly in a dry pan, then blended until smooth — a process that takes two to four minutes in a high-powered blender or food processor.
What Drives the Cost Difference
The biggest variable is the sesame seed price. Bulk bins at natural food stores or wholesale clubs often stock raw or hulled sesame seeds for $3 to $5 per pound, which makes homemade tahini significantly cheaper per ounce than premium jarred versions. If you are buying small retail bags at $6 to $8 per pound, the math gets much tighter. The oil used is a small fraction of the cost — typically one to two ounces per batch — so its impact is minimal unless you are using an expensive specialty oil.
Blender energy is nearly negligible: a 1,000-watt motor running for two minutes consumes roughly 0.03 kWh, costing less than half a cent at average US electricity rates.
Quality Factors Beyond Cost
Homemade tahini lets you control roast level, seed variety, and salt content. Store-bought versions vary widely in bitterness and texture. Many home cooks find that once they have made their own, the superior freshness and flavor justify the effort regardless of whether it saves money.
Frequently Asked Questions
How much tahini does one pound of sesame seeds make?
One pound (16 oz) of sesame seeds yields approximately 14 to 15 oz of tahini after toasting, as the seeds lose a small amount of moisture during the toasting step. Adding one to two ounces of oil brings the final volume back up to roughly 15 to 17 oz, depending on how much oil you use and your preferred consistency.
Do I need a high-powered blender to make tahini?
A high-powered blender (Vitamix, Blendtec, etc.) produces the smoothest tahini in the shortest time. A standard food processor will also work but may take five to eight minutes and produce a slightly grainier texture. A regular countertop blender can struggle with the thick paste and may overheat. The blender you already own is the best one to start with.
Should I use hulled or unhulled sesame seeds?
Hulled (white) sesame seeds produce the mild, creamy tahini most common in Middle Eastern cooking and store-bought jars. Unhulled seeds yield a darker, more bitter paste with slightly higher calcium and fiber content. Most recipes and commercial brands use hulled seeds, so they are the better starting point if you want a flavor that matches what you are used to.
Where can I buy sesame seeds cheaply to make homemade tahini worth it?
Bulk sections at natural food stores, Middle Eastern or South Asian grocery stores, and warehouse clubs consistently offer the lowest per-pound prices for sesame seeds — often $2 to $4 per pound versus $6 to $9 for small retail bags at conventional supermarkets. Online bulk sellers can also be competitive when you buy 5 lbs or more.
How long does homemade tahini last?
Stored in a sealed jar in the refrigerator, homemade tahini keeps for four to six weeks. Since it contains no preservatives, the natural oils can go rancid faster than commercial versions. You can also freeze tahini in portions for up to six months. Oil separation is normal — just stir before use.
