Rootle
Rootle is a sustainable, healthy ingredient substitution engine built for the kitchen.
It analyses the chemical flavor compounds in over 935 ingredients to find swaps that actually taste right, not just swaps that exist on paper. Every suggestion is ranked by carbon footprint and compared nutritionally so you know exactly what you are trading and what you are gaining.
How it works
Rootle maps ingredients against a database of 1,792 flavor molecules. When you search for an ingredient or a recipe from our library of 44,000+, it surfaces the alternatives that share the most molecular overlap, meaning the swap holds up when you cook it.
Carbon data is shown per ingredient in a simple low/medium/high scale. Nutritional differences are surfaced side by side. No guesswork, no AI.
Novel and Underutilised Species
A core part of Rootle's mission is surfacing NUS foods: ingredients like jackfruit, spirulina, amaranth, and seaweed that are nutritionally dense, low-carbon, and almost entirely absent from mainstream cooking. Rootle surfaces them as first-class alternatives, with context on why they matter.
The impact
Food production accounts for more than a quarter of global greenhouse gas emissions. Most of that impact is invisible at the moment of decision, which is when it matters most. Rootle puts the information directly in front of you, framed around a choice you are already making.
Small swaps, made consistently, add up.
