The Wednesday’s family eats very unusual food.

And… have aam in the mood to write today.

By the way, off the topic, I remember that old movie Addams Family, 1991, staring Christopher Lloyd (he appears in 2th season of Wednesday, too).

no need for by the way and off topic

There’s typical cliche scene in the movie – the dance Mahushka – “…A Kozak taught us this dance!

typical and cliche are not both needed

The Western people never eat themat, don’t they?

I heard that if you haven’didn't eaten buckwheat porridge fromduring childhood (like Polish and Ukrainian people do), you will never accept its taste – it can have some sense, but Stuhden is meat and dense bouillon justis cold.

I'm not sure what you mean by it can have some sense.

For people drinking with meals ice tea or ice cola… T with meals, try студень with ice brandy.

Also ther’s Khash inThere's also Khash, which is Armenian cousin.

This dish has the same ingredients and is cocoked the same way, but it’s eaten hot.

Next, something personal.

I’m a food outcast.

"food outcast" isn't a typical saying, but I understand what is trying to be said.

I don’t eat fish, salo (I’m not a vegetarian and I don’t have allergy), pluck (except tongue).

I have low hemoglobin now – it's such a pity I neverwon't try blood sausage.

Life is so hard… (a jokejust kidding, don’t take to heart).

Just kidding is used to express that one was joking.

Strange Tastes and Habits

'Tastes' and 'habits' are separate things, and should be separated.

I watched the Wednesday series.

'Wednesday' is a specific series, and needs 'the' before it.

The Wednesday’s family eats very unusual food.

Surnames do not need -'s at the end.

And I have a topic about food habits in my reservelso, I am going to talk about people's food habits soon.

This is a very unnatural transition. If this is something completely informal, it's fine, but usually you want to combine your topics so that each one transitions smoothly in blocks.
This sentence should not start with 'and', as it does not connect anything. Something like:
"Also, I am/I'm going to/gonna talk about people's food habits soon," would be more correct, as 'in my reserve' also sounds awkward, as a 'topic,' being conceptual, isn't something you can really have.

And… have aI am in a/the mood to write today.

You would say you're *in* a mood.

By the way, off the topic, I remember that old movie Addams Family, 1991, staring Christopher Lloyd (he appears in 2th season of Wednesday, too).

You can omit it in this case, but to refer to a previous topic, you would say, 'off this topic,' or, 'off the previous topic.' Natives are used to using and hearing 'off-topic,' however, so it sounds awkward.

There’s a typical cliche scene in the movie – the dance Mahushka – “…A Kozak taught us this dance!

Indefinite article 'a' needed here.

Hey!...” There’s no such a word, by the way.

Well, let’s return to our foods.

We won’t be talking about Surströmming, Igunaq/ kopalgyn, some Asian extremal exotic, etc.

For an appetizer starting with Stuhden/Hohlohdetc/Aspic and buckwheat porridge.

The Western people never eat them, don’t they?

The negative would not be used here, as it creates kind of a double negative (although it's mostly just nonsensical.) Negatives are only used when the preceding positive is positive.
Example: "He does eat rice, doesn't he?"

I heard that if you haven’t eaten buckwheat porridge from childhood (like Polish and Ukrainian people do), you never accept its taste – it can have some sense, but Stuhden is meat and dense, and boullon just cold.

For people drinking with meals iced tea or iced cola… Try студень with iced brandy.

Also there’s Khash i, an Armenian cousin.

This dish has the same ingredients and its cocoked the same way, but it’s eaten hot.

Next, something personal.

I don’t eat fish, salo (I’m not a vegetarian and I don’t have allergy), pluck (except tongue).

Life is so hard… (a joke, don’t take it to heart).

I heard about a man who didn’t eat tomato if it was cut.

Children usually hate milk skin.
