‘Ulu flour is made from breadfruit, a starchy tropical fruit that grows on trees brought to Hawai‘i by Polynesian voyagers more than 1,000 years ago. Today, ‘ulu is a largely underutilized crop that produces an abundance of nutritious fruits with extremely low shelf life. At the same time, Hawai’i now imports nearly 100% of its staple foods, including virtually all of its flours.
Given the need to increase food security and decrease food waste, drying and milling breadfruit into flours offers a promising way to extend the fruit’s shelf life while creating a local, sustainable, and high-quality staple for local consumption, with significant export market potential.
With the recent increase in commercial ‘ulu production throughout Hawai‘i, ‘ulu flour production is also increasing. This guide is intended to support new ‘ulu flour users to incorporate this wonderful product into home and commercial cooking and baking.
Ulu flour absorbs more liquid than all-purpose (AP) or bread flours, so depending on the recipe used, one may need to add more liquid to compensate.
Ulu flour can impart a unique breadfruit-like flavor, with “whole fruit” flour more so than peeled. This should be factored into deciding how much ‘ulu flour to substitute for other flours in recipes as well as which type of ‘ulu flour to use.
Suggested supplemental ratios
A recommended supplemental ratio of ‘ulu flour to AP flour is 50:50 in recipes that include a substantial amount of liquid and ingredients with combative flavorings (e.g. banana bread). A ratio of 30:70 ‘ulu flour to AP flour is recommended for recipes that call for less liquid and/or little to no additional flavorings (e.g. pizza dough, shortbread), unless stronger ‘ulu aroma and flavor are desired.
