Vegan hot dogs with mayonnaise and stewed onions

Hi guys. This is my first time posting here but I'm really proud of the dinner I cooked today for my girlfriend.
As per title, I made an hot dog with mayonnaise and stewed onions.
I will write you the recipe and some advices on what I would do next time

HOT DOGS

For the hot dog I followed the recipe I found on Instagram. You can follow every step there, but here are the ingredients:

240 g cooked red beans

2 teaspoons paprika

1/2 teaspoon fennel seeds

1 pinch nutmeg

1 teaspoon garlic powder

1 teaspoon chopped rosemary

1 pinch black pepper

1 tablespoon miso

120 g water

Juice of 1/2 lemon

150 g wheat gluten

About 2.5 L vegetable broth

You first add and blend all the ingredients except for gluten. Add the gluten and mix (the same way you would mix bread) and then shape them and cook them into a vegetable broth for 45 minutes. After that let them cool down and cook them on a grill (as I did) or as you prefer!

What I did different and what I would change next time:
1) I used one teaspoon of paprika (half spicy half smoked). Next time I would probably use spicy pepper or just nothing at all. If you want a smoked flavour use liquid smoke!
2) I come from a place where sausages are made by adding fennel so if I want to feel like I'm eating one I need to feel the taste of fennel seeds. In the recipe, I blended a teaspoon with all the other ingredients and added some more while mixing the dough. Next time I would add more without blending any of them, since I didn't feel the taste at all.
3) I added soy sauce instead of miso (I just didn't have it)
4) I didn't add nutmeg (I forgot), but I don't think I would have enjoyed it.
5) the colour is awful, so it's probably better to use white beans or something that make them super red (like beetroot juice)
6) add salt (maybe 1% or 2% of the gluten weight) while kneading the dough, as I got a bland taste adding it after.
7) while grilling I applied some olive oil to cook for a better cooking
8) I added thyme instead of rosemary

The taste was good but if you adjust the recipe they will taste wonderful.

MAYONNAISE

For the mayo I took inspiration from a Kenji's recipe . The first time I made it, it didn't come out too well (I didn't use mustard seed and it was very runny).
I wanted a more authentic mayo without any other taste. After a bit of studying I discovered the existence of xanthan gum and it's uses. It can emulsify better than lecithin and can stabilise the emulsion. This is the recipe that came out of this experiment (credit to chatgpt ahha)

45 ml aquafaba (liquid from canned chickpeas)

5 ml lemon juice

120 ml neutral vegetable oil (e.g., sunflower, canola)

0.3 g xanthan gum (about ¼ tsp, leveled) (I used a precision scale for this)

1 pinch of salt

(Optional: 1 tbsp cooked chickpeas to give structure to the mayo)

First you mix all the ingredients except for oil. Add the oil, mix with an immersion blender at the bottom without moving and after 5/10 seconds you can start moving (just like a normal mayonnaise).
The consistency was just perfect. Put it in the fridge if you don't use it right away, as it will become less thick over time.

What I would do differently:
1) unsurprisingly, it didn't have a strong taste of nothing. Next time I would use mustard seeds or roasted garlic.
2) use more salt than I did

STEWED ONIONS

This is quite easy.
Use as many onions as you need (I used to little ones for two people). Cook them over high heat until they don't release water anymore, than add some red wine, lower the heat and let them cook more (cover the pan) untill they are soft but not mushy. After that few seconds more without the lid and in high heat again to eliminate the residual alcohol.
You could add some spices as well.

Let me know if you make them 🙂 next time I will try making the buns as well!

PS: sorry for typos or errors. It's 1 am and I don't want to read the post again ahah

Love you
