Ube (Purple Yam) substitute

Substitutes for Ube (Purple Yam) with ratios

1. 2Ube halaya (ube jam)

   Close match

   Use the same amount by volume for mashed cooked ube, then cut the recipe's sugar by about a third and its butter by half

   Ube already cooked down with condensed milk, sugar and butter, which is why it is the fastest route into a cheesecake, ice cream or bread filling.

   What changes

   Best for

   ube cheesecake, ube ice cream and halo-halo, filling for pandesal and rolls, ube buttercream

   The flavour is deeper and more caramelised than plain mashed ube, and the colour is usually more purple because most commercial halaya includes colouring. Because it is already sweetened and enriched, a recipe that does not have its sugar and fat pulled back comes out cloying and greasy. In a bread dough, halaya also adds enough sugar to slow the yeast, so allow a longer rise.

2. 3Ube powder (dehydrated purple yam)

   Different taste

   ¼ cup powder whisked into ¾ cup hot milk or water equals about 1 cup mashed ube; rest 15 minutes

   Shelf-stable, cheap, and genuinely made from ube, which puts it well ahead of extract as a flavour source even though it is weaker than the fresh root.

   What changes

   Best for

   cakes and cupcakes, pancakes and waffles, drinks and lattes, anywhere you cannot spare fridge space

   Hydrated ube powder tastes dustier and less sweet than fresh, closer to a mild taro, and its colour is a muted greyish lavender rather than violet. Let it sit the full fifteen minutes or you get gritty specks in the crumb. A quarter teaspoon of ube extract per cup fixes the colour and aroma if you have any; if not, the cake is still good, just quieter and paler.

3. 4Okinawan or Stokes purple sweet potato

   Taste and texture differ

   Use the same amount by weight steamed and mashed, minus 2 tablespoons sugar per cup of puree

   The best fresh-produce swap in a Western supermarket, and the reason so many cafe ube desserts are secretly purple sweet potato.

   What changes

   Best for

   ube ice cream and soft serve, cakes, muffins and pies, purple mashed side dishes, anything where colour matters more than authenticity

   Purple sweet potato is noticeably sweeter and much wetter than ube, and it tastes like sweet potato, with none of ube's nutty, faintly coconut and vanilla quality. Cut the sugar or the dessert becomes sickly, and reduce other liquid by a couple of tablespoons per cup or a cake batter will slump. Okinawan sweet potato has genuinely purple flesh and is the better pick; Stokes runs more magenta and turns slightly blue-grey in an alkaline batter. Do not use ordinary orange sweet potato and expect anything purple.

4. 5Taro (gabi)

   Different taste

   Use the same amount by weight steamed and mashed

   The right texture answer and the wrong colour answer.

   What changes

   Taro is starchy, dry and mashes to the same dense, slightly sticky puree ube does, which makes it the closest textural match on this list.

   Best for

   halo-halo, bubble tea and drinks, steamed cakes and buns, puddings where colour can be adjusted

   Taro is pale cream flecked with lilac, not purple, so any dessert made with it looks grey-beige unless you colour it. The flavour is earthier and more savoury than ube, less sweet, and closer to a chestnut. It is a fine swap in a drink or a pudding and an obvious one in a cake meant to be violet. Handle raw taro with gloves, as the raw sap irritates skin, and always cook it fully.

5. 6Russet potato plus ube extract (the least-bad option)

   Different taste

   1 cup riced cooked russet plus 1 teaspoon ube extract for 1 cup mashed ube

   The honest bottom of the list, for when you need an ube pandesal or ube bread tonight and have nothing purple in the house.

   What changes

   Best for

   ube pandesal or enriched bread dough, ube cheese pandesal, situations with no Asian grocery within reach

   Potato gives you the starch, softness and moisture that make ube bread tender, and the extract gives colour and a vanilla-ish aroma. What you do not get is any ube flavour, because the extract is mostly dye and perfume. The result is a very good soft purple roll that does not taste of ube, and it is worth being clear-eyed about that rather than disappointed. Rice or pass the potato through a sieve while hot, since mashing hard makes it gluey.
