Если делать омлет аккуратно, венчик и лопатка очень помогают.

This is a common Russian way to make a general, impersonal statement.

Если делать омлет аккуратно means something like if you make / when making an omelet carefully, where you means people in general, not one specific person.

Russian often uses the infinitive this way when:

• the subject is generic,
• the sentence sounds like advice or a rule,
• the focus is on the action itself rather than on who is doing it.

A more personal version would be:

• Если ты делаешь омлет аккуратно... — if you are making an omelet carefully...

The infinitive version sounds broader and more neutral.

Because Russian often does not mention a subject when it is meant generically.

In English, advice often uses you:

• If you make an omelet carefully...

Russian can express the same idea without saying ты or вы. In this sentence, the infinitive construction already carries that general meaning, so no explicit subject is needed.

So the sentence is complete as it is; nothing is missing.

Делать is imperfective, and that fits this sentence because it gives a general piece of advice about the process.

The point is not to complete one omelet once, but rather the activity of making omelets carefully in general.

Compare:

• делать = to make, to be making, to make in general
• сделать = to make/finish once, to complete

With если in a general statement like this, делать is the natural choice.

Омлет is in the accusative case, because it is the direct object of делать.

But for an inanimate masculine noun like омлет, the accusative looks the same as the nominative:

• nominative: омлет
• accusative: омлет

So the form does not change, but the grammatical case is still accusative.

They are in the nominative case because they are the subject of the main clause.

They are the things that help, so Russian uses the nominative:

• венчик — whisk
• лопатка — spatula
• венчик и лопатка — whisk and spatula

That subject then controls the verb form помогают.

Because the subject is венчик и лопатка — two nouns joined by и.

In Russian, two subjects joined by и normally take a plural verb:

• венчик помогает — the whisk helps
• лопатка помогает — the spatula helps
• венчик и лопатка помогают — the whisk and the spatula help

So the plural verb is exactly what you would expect here.

Yes. Очень can modify verbs as well as adjectives.

With adjectives:

• очень полезный — very useful

With verbs:

• очень помогает — helps a lot / helps greatly

So here очень помогают does not have to be translated word-for-word as very help. In natural English, it is usually better as:

• help a lot
• help greatly
• really help

Literally, если means if. But in a sentence like this, the overall meaning is more like general practical advice, so in English it can feel close to when or whenever.

The sentence is not really about one specific future situation. It is more like a general rule:

• if/when you make an omelet carefully, these tools help

So если is still correct and normal, but the nuance is broader than a one-time conditional.

Аккуратно can mean carefully, neatly, tidily, or sometimes gently, depending on context.

In a cooking sentence like this, it suggests doing something:

• carefully,
• in a controlled way,
• without making a mess,
• without damaging the food.

So it is not just abstract carefulness. It has a very practical, hands-on meaning here.

Because Если делать омлет аккуратно is a subordinate clause introduced by если, and it comes before the main clause венчик и лопатка очень помогают.

Russian normally separates this structure with a comma:

• Если ..., ...

This is similar to English:

• If you do X, Y helps.

Yes, лопатка has several meanings.

Depending on context, it can mean:

• spatula / turner in the kitchen,
• shoulder blade in anatomy,
• a kind of small shovel/spade in other contexts.

Here, because the sentence is about making an omelet, it clearly means a kitchen spatula.

Yes. Russian word order is fairly flexible.

For example, you could also say:

• Венчик и лопатка очень помогают, если делать омлет аккуратно.

Both versions are grammatical. The difference is mainly one of focus:

• Если делать омлет аккуратно, ... puts the condition first.
• Венчик и лопатка очень помогают, ... puts the main point first.

The original order sounds natural for giving advice or explaining a general rule.
