🛒 Ingredient Tips
The key to this sauce lies in the freshness of the tomatoes and onions.
Choose tomatoes with smooth, firm skins that feel heavy for their size.
Look for fresh, green stems and avoid overly soft or bruised ones.
For onions, select those with shiny, firm skins and no mold at the root end.
Three large onions are ideal, but if using smaller ones, use four to fully bring out their sweet flavor, which will deepen the sauce's richness.
Using seasonal tomatoes and onions will maximize their natural flavors without the need for artificial sweetness.
🔄 Substitution Guide
If you have a tomato allergy or fresh tomatoes are hard to find, you can use canned tomatoes.
Use 2-3 cans of whole peeled tomatoes (about 14 oz / 400g each).
In this case, the acidity of the tomatoes might be stronger, so increase the amount of sugar slightly or add a tablespoon of honey to balance the flavor.
If you don't have bay leaves, you can omit them, but if you want to add an herbal aroma, you can add about 0.5 tsp of dried herbs like oregano or basil for an exotic touch.
If using garlic powder instead of fresh garlic, use only about 1/2 tsp.
However, remember that using fresh ingredients will yield the deepest and richest flavor.
🥘 Ingredients
👨🍳 Cooking Points
There are two crucial cooking points for this recipe.
First, it's important to sauté the onions sufficiently to bring out their sweetness.
Sauté them over medium heat for 5-7 minutes until they become translucent and a sweet aroma emerges.
Be careful not to cook them over too high heat, as they may burn and develop a bitter taste.
Second, reduce the sauce sufficiently to achieve the right consistency.
After adding and cooking the tomatoes, season with salt, then simmer over low heat for 25-30 minutes with the lid slightly ajar.
It's important to stir occasionally to prevent sticking to the bottom.
The ideal consistency is when you can briefly see the bottom of the pot when pushing the sauce with a spatula, so be careful not to reduce it too much.
👨🍳 Directions
Wash the tomatoes thoroughly under running water, then cut off the stem end and any bruised or soft spots. If you prefer to remove the skin, blanch them in boiling water for about 30 seconds, then transfer to cold water and peel the skin. Cut the tomatoes into large chunks.
Peel the onions, halve them, and then roughly julienne. Mince or slice the garlic.
Heat 2-3 tablespoons of olive oil in a heavy-bottomed pot over medium heat. Sauté the onions for 5-7 minutes until they become translucent and a sweet aroma develops. (Be careful not to cook over too high heat, as they may burn.)
Once the onions are translucent, add the garlic and sauté until fragrant. (Do not overcook, or it may develop a bitter taste.)
Add all the chopped tomatoes, cover the pot, and simmer over medium heat for about 10 minutes. (Do not add water; the tomatoes will release their own moisture.)
After 10 minutes, when the tomatoes have softened and released their juices, mash the tomatoes with a spatula. (If you prefer a smoother sauce, lightly blend it with an immersion blender.)
Add 1 teaspoon of salt and reduce the heat to low. Continue to simmer with the lid slightly ajar for another 25-30 minutes. (Stir occasionally to prevent sticking to the bottom.)
The sauce is done when its color deepens and it thickens. (A good consistency is when you can briefly see the bottom of the pot when pushing the sauce with a spatula. Be careful not to reduce it too much.)
Taste and adjust seasoning by adding more salt, 0.5 tsp sugar, black pepper, or 1 bay leaf according to your preference.
Do not seal the hot sauce immediately. Let it cool completely before transferring to a clean container for storage.
💡 Tips
Sautéing the onions sufficiently first to bring out their sweetness helps to mellow the acidity of the tomatoes, allowing you to make a delicious sauce with less sugar.
This sauce can be used in various dishes such as rice, egg dishes (fried eggs, scrambled eggs), meat dishes (pork, chicken), fish dishes (mackerel, Spanish mackerel), noodle dishes (noodles, pasta, ramen), and bread dishes (toast). Adding the sauce to each dish will enhance its flavor and aroma.
Since this is a base sauce, it's best not to make it too salty initially, as this allows for more versatility in various dishes. Adjust the seasoning to your liking when serving with specific meals.
Tomatoes are acidic, so individuals with sensitive stomachs or acid reflux should be cautious not to consume too much on an empty stomach. Onions can also cause bloating in some people, so try a small amount first.
Refrigerate the sauce and consume within 3-5 days. For longer storage, divide it into single-serving portions, spread thinly in freezer bags, and freeze. This makes it easy to break off portions as needed and thaws quickly. (Room temperature storage without professional sterilization is risky.)
📦 Storage & Reuse
The finished sauce must be completely cooled before being stored in a clean, airtight container.
When refrigerated, it can be enjoyed fresh for about 5-7 days.
If you wish to store it longer, it's recommended to divide it into single-serving portions and freeze them.
Frozen, it can be stored for about 1-2 months.
To thaw, simply move it to the refrigerator for natural thawing or gently warm it in the microwave.
Leftover sauce can be mixed with rice, topped on a fried egg for a simple meal, or used as a sauce for chicken or pork dishes – ensuring no delicious bit goes to waste.
🥢 Who This Is For
This versatile sauce is especially recommended for busy working mothers or those who frequently dine alone.
Preparing it in advance allows for easy incorporation into various dishes, from breakfast to dinner, enhancing your quality of life.
For family meals, you can serve it with pork steak or grilled chicken breast for a wonderful dish.
For children's snacks, topping toast or scrambled eggs with it makes a nutritious meal.
It's also delicious mixed with rice or used as a pasta sauce.
