Banana Ketchup
Banana Ketchup · A sweet-tangy Filipino condiment made by simmering puréed ripe bananas with aromatics, vinegar, and sugar until thickened, then seasoned and typically tinted red to mimic the appearance of tomato ketchup. Created in the 1930s–40s as a tomato-substitute during wartime shortages.

The formula
3 parts banana purée : 1 part vinegar : 1 part sugar (by volume, approximate)
Proportions vary by source; vinegar and sugar are scaled for sweet-sour balance, aromatics ~10% by weight.
Identity
- Filipino national condiment invented by food scientist María Orosa in the 1930s
- Tomato-free ketchup substitute born of WWII tomato scarcity and Philippine banana surplus
- Sweet-sour-savory profile colored red (artificially or with tomato paste) to mimic tomato ketchup
- Smooth purée thickened by reduction, not by added starch
- Keeps refrigerated for weeks; a pantry-stable bottled condiment in the Philippines
Ingredients
| Base | Ripe bananas (saba or common Cavendish), sliced or mashed | Provide sweetness, body, and the signature fruity backbone; very ripe fruit gives best flavor. |
| Acid | Cane vinegar or distilled white vinegar | Provides tang and shelf stability; cane vinegar is traditional. |
| Sweetener | Brown or white sugar | Balances acidity and amplifies banana sweetness; brown sugar adds depth. |
| Aromatics | Onion, garlic, and fresh ginger | Sautéed base that builds savory depth against the fruit. |
| Seasoning | Salt | Heightens sweetness and rounds flavor. |
| Seasoning | Ground turmeric and/or black pepper | Adds warm color and gentle spice; some versions use a spice sachet. |
| Flavor | Red food coloring or tomato paste | Traditional commercial versions use artificial red dye; modern/traditionalist recipes skip it or use tomato paste. |
Method
- 1Sauté onion, garlic, and ginger in oil until soft and fragrant.Builds the savory aromatic base and softens the alliums for smooth blending.
- 2Add bananas (and a splash of water if needed) and simmer until very soft.Breaks down the fruit to release sugars and develop the purée.
- 3Purée the cooked mixture until smooth, then return to the pan.Creates the characteristic smooth ketchup texture.
- 4Stir in sugar, vinegar, salt, and spices; bring to a gentle simmer.Dissolves sweetener, balances sweet-sour-salty, and infuses spice.
- 5Reduce over low heat until thick enough to coat a spoon.Evaporates moisture to ketchup-like consistency without needing starch.
- 6Stir in red food coloring or tomato paste if using; adjust seasoning.Recreates the iconic red color and final flavor balance.
- 7Cool slightly, bottle, and refrigerate.Prevents spoilage and lets flavors meld.
Techniques that matter
Sweating aromatics
Softens alliums without browning, keeping the flavor clean and sweet for the fruit base.
Simmer-reduction thickening
Achieves ketchup viscosity naturally from pectin-rich banana rather than added starch.
Spice sachet infusion
Allows whole spices to flavor the sauce without leaving gritty bits in the purée.
Variations & derivatives
Classic Juana Orosa-stylePhilippines
Original wartime recipe using only bananas, sugar, vinegar, and spices; no tomato paste or dye.

Used in these dishes
Substitutions
- Ripe bananas → Ripe saba (plantain) bananas — More traditional; gives earthier, less sweet flavor.
- Cane vinegar → Distilled white vinegar or apple cider vinegar — White is sharper; cider adds fruity depth.
- White sugar → Brown sugar or palm sugar — Brown/palm sugar adds molasses notes and deeper color.
- Artificial red food coloring → Tomato paste or beet juice — Provides red hue naturally though flavor profile shifts slightly.
Troubleshooting
Ketchup is too thin and runny
Insufficient reduction or high-moisture bananas → Simmer longer over low heat, or add a small amount of tomato paste to thicken.
Ketchup is too sweet
Too much sugar or overripe bananas → Add more vinegar and a pinch of salt to rebalance.
Ketchup is too sour or sharp
Too much vinegar or undercooked sugar → Stir in additional sugar and simmer briefly to dissolve.
Color is dull yellow instead of red
No dye/tomato paste added, or bananas weren't ripe enough → Stir in red food coloring, tomato paste, or a splash of beet juice while warm.
