SunButter No Sugar Added (line)

A sunflower seed butter that spreads and bakes much like peanut butter, and the brand makes it in a facility free of peanuts and tree nuts, so it works for allergy-restricted households, schools and lunchboxes.

Not for: People without nut allergies who want the classic flavour of peanut or almond butter, and bakers using baking soda who don't want sunflower's harmless green discoloration.

Smucker's Natural Creamy Peanut Butter

Just peanuts and salt, with rich roasted flavor and a creamy texture versatile enough for toast, sauces, and baking.

Not for: People with peanut allergies or those who prefer no-stir spreads.

Which one fits you

tahini for hummus and dressings

Soom Premium Tahini (line)

A pourable, smooth sesame paste made from a single ingredient that tastes nutty rather than bitter.

Not for: Anyone avoiding sesame, or anyone wanting a sweet toast spread.

Check before you buy

Ingredient list. Best: nuts or seeds alone, or with salt. Added palm oil is acceptable as a no-stir stabilizer. Reject hydrogenated oils. Fewer additions mean truer flavour, and fully or partially hydrogenated oils are the main thing separating cheap spreads from real butters.
Allergen facility. For allergies, look for an explicit dedicated-facility or 'free from peanuts and tree nuts' statement, not just a nut-free ingredient list. Seed and coconut butters are often made on shared lines with peanuts and tree nuts.
Oil separation. Natural (unstabilized) butters separate. Stir fully once, then refrigerate. Stabilized butters stay mixed at room temperature. If you dislike stirring, you will end up with a dry bottom half, so choose stabilized deliberately rather than by accident.
Roasted vs raw. Roasted for deeper flavour and toast. Raw for a milder, sweeter taste and for raw-food recipes. Roast level changes flavour more than brand does.

What to avoid

Products labelled 'spread' when you wanted pure butter: the name usually means added sugar, oils or fillers.
Hydrogenated or partially hydrogenated oils in the ingredient list.
Assuming a nut-free ingredient list means allergy-safe without checking the facility statement.

Questions

Why does my natural butter have oil on top?

Without stabilizers the nut's own oil separates. Stir it back in fully, then keep the jar refrigerated to slow re-separation.
