About ounces Tomato Paste (ounces)
Ounces of Tomato Paste. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL). Tomato paste is concentrated tomato puree — fresh tomatoes (Solanum lycopersicum, typically processed varieties like Roma + San Marzano) cooked for hours to remove water, then reduced to a thick + intensely flavored paste of ~30% tomato solids per USDA Standards for Grades. Density ~1.100 g/mL (denser than water due to high concentration of tomato pulp + sugars + proteins + fibers). 1 6-oz can = ~170 g; 1 tablespoon ≈ 16 g. Major US brands: Hunt's (ConAgra), Contadina (Conagra), Cento (premium Italian-imported), Mutti (Italian DOP-quality), Bionature Organic. 'Tube' style (Mutti, Cento, Amore — squeezable aluminum tubes 4-6 oz) is preferred by professional chefs because you can use 1 tablespoon without opening + discarding a full 6-oz can. Triple-concentrated (28-30% solids) is the US grocery standard; 'double-concentrated' (25-28%) is European; 'single-concentrated' (12-25%) is sold as 'tomato puree' or 'passata' rather than 'paste'. Foundational ingredient in: pasta sauces (marinara base), pizza sauce, chili, beef stew, Indian curries (tomato-based gravies), shakshuka, BBQ sauce base, tomato bisque + soup intensifier. Density: 1.100 g/mL (used to convert volume measurements to mass).
About cups Tomato Paste (cups)
Cups of Tomato Paste. Measured by US cup (= 240 mL = 16 US tablespoons = 48 US teaspoons per FDA 21 CFR 101.9). The cup is the dominant US baking + cooking volume unit, but actual density varies significantly by how the ingredient is packed (scooped vs spooned-and-leveled — a 1-cup scoop of flour can range from 110 g to 150+ g depending on technique, which is why precise bakers use mass measurement in grams). Always level with a flat edge (the back of a knife) for accurate volumetric measurement.
