Gum arabic substitutes

A modern fermentation-derived gum that thickens and suspends in cold liquid.

Best for

cocktail gum syrup, flavoured syrups, soft drinks and sodas, keeping spices or oils suspended

Pay attention to the ratio, because this is where people go wrong: xanthan is many times stronger than gum arabic, and matching it spoon for spoon gives you slime. Used correctly it holds oils and particles in suspension just as well. What changes is the mouthfeel: gum arabic is clean and silky and disappears, while xanthan is faintly slippery and, if you overshoot even slightly, ropy. It also does nothing to stop sugar crystallising. Blend it in with an immersion blender or whisk it into the dry sugar first, because it clumps instantly in water.

The no-shopping answer for cocktails, using sugar concentration instead of gum for body.

Best for

old fashioneds, gin fizzes, any recipe calling for gum or gomme syrup, iced coffee and tea

Honest and practical: most people buying gum arabic are trying to make gomme syrup for cocktails, and a two-to-one rich syrup delivers the same sweetness at the same dose. What you lose is the specific viscous, mouth-coating silkiness that is the whole point of gomme, so the drink tastes right but feels leaner and the texture reads as watery next to a proper gum syrup. Dissolve the sugar in warm rather than boiling water so it does not reduce and throw off your ratio.

The closest botanical and functional relative, also a tree gum, traditionally used for sugar work.

Best for

gum paste and sugar flowers, pastilles and lozenges, royal icing, edible glue

For the cake-decorating and confectionery jobs this is the true equivalent, and classic gum paste recipes were built on it before CMC arrived. It hydrates into a stringier, more elastic gel than gum arabic, which is exactly what you want for petals you need to roll thin and dry hard. It is slightly stronger, so start below a straight swap. It is also expensive and about as hard to find as gum arabic, which is its main drawback.

The cake-decorating standard for stiffening fondant and making edible glue.

gum paste, sugar flowers, edible glue, stiffening fondant

Widely stocked wherever cake supplies are sold, and it does the film-forming and hardening job cleanly. The differences are practical: tylose sets faster and dries harder and more brittle than gum arabic, and a glaze made with it is matte rather than glossy. Because it is stronger, half the weight is a sensible starting point. It is no help at all for drinks or syrups, where it goes gluey.

An invert sugar that stops crystals forming, covering gum arabic's anti-graining role.

Best for

hard candy, fruit pastilles, sugar syrups stored for weeks, glazes

If the reason your recipe lists gum arabic is that a syrup or candy kept turning grainy, this is the correct fix and it is easier and cheaper. It does not emulsify anything, so it will not hold flavour oils in suspension or keep a cloudy syrup homogeneous. It also adds real sweetness where gum arabic adds none, so trim the recipe's sugar by roughly the amount of syrup you add if the result would otherwise be too sweet.

Protein foams that stabilise bubbles and dry to a film, covering the foam and glaze jobs.

Best for

royal icing, foamed cocktails, marshmallow and nougat, brushing pastry for shine

Good for the specific jobs where gum arabic is holding a foam or forming a shiny surface. The trade-offs are real: a protein foam collapses within hours where a gum-stabilised one lasts days, it cannot be stored at room temperature, and it behaves differently around strong acid and alcohol, thinning noticeably in a spirit-heavy drink. Aquafaba is the vegan route and gives a slightly softer, less stable foam than egg white.
