Sweet and Sour Cabbage, Second Draft

I'm more nearly there, I think,  but the recipe still needs some work.
I went in a different direction, foregoing ketchup entirely and using canned pineapple bits in syrup, which happen to be sweet and sour.

Ingredients:

Sauce
1 Cup chicken broth
1/4 Cup Rice vinegar
1/4 Cup white sugar cane vinegar
1/3 Syrup from canned pineapple bits
210 Gr.tomato puree
1 Teaspoon powdered turmeric
3 Tablespoons Soy sauce (low sodium)
3 Tablespoons corn starch dissolved in 1/4 cup of water

1/2 Head of green cabbage
1 Carrot, cubed.
1 Cup snow peas
1 Red onion in thin slices
2 Cloves garlic
1 Teaspoon sesame seeds
1 Cup pineapple bits, drained of syrup

For the sauce mix the chicken broth, both types of vinegar, syrup, tomato puree, turmeric and soy sauce in a  bowl and whisk vigorously. Set aside. As always, taste it and adjust ingredients to your taste.

In a pot heat some olive oil. Saute the onion and garlic for a few minute, then add the sesame seeds and saute for another two minutes. Add the cabbage, carrot and snow peas. Don't add the pineapple yet. Stir fry until the vegetables soften a little. Reduce heat to minimum and add the sauce and pineapple. Stir well so everything is well covered in the sauce.

Let the dish come to a slow boil. When it boils, add the corn starch solution and stir well, again making sure everything gets well covered. You'll feel the sauce thicken while you stir. Let it simmer for a minute or two, let it cool a bit and serve.

I'm not satisfied with the dish as it is, or with the sauce. But I think I'm headed in the right direction. I'll likely rest from sweet and sour, and tomato puree (see following post, eventually) for a week or two, then get back to it.

But the way, the sauce does look a little more red than it shows in the photo.
