haha ha nabe de yasai ya niku wo yoku nite kara, saigo ni miso wo mazeru.

は marks 母 as the topic of the sentence: As for mother, ...

That means the sentence is presenting what the mother does, rather than strongly identifying her as the doer in contrast to someone else.

• 母は... = As for my mother, ...
• 母が... would put more focus on mother as the subject, often sounding more contrastive or answering Who does this?

In a normal descriptive sentence like this, は is very natural.

In Japanese, family terms like 母 often mean my mother when used in a sentence without extra explanation.

So here, 母 is most naturally understood as my mother.

A useful contrast:

• 母 = my mother when talking to others
• お母さん = often mom or someone else’s mother, depending on context

Here, で marks the place or means where the action happens.

So 鍋で means:

• in a pot
• or more literally, using a pot

In cooking sentences, で is commonly used this way:

• フライパンで焼く = cook/grill in a frying pan
• 鍋で煮る = simmer in a pot

So 鍋で tells you the cooking is being done in a pot.

や is used to give an incomplete list: things like vegetables and meat.

So:

• 野菜や肉 = vegetables, meat, and possibly other things
• 野菜と肉 = vegetables and meat only, as a more complete or fixed pair

In cooking descriptions, や is very common because the speaker may just be naming some representative ingredients.

Because 野菜や肉 works together as one object phrase.

So the structure is:

• 野菜や肉を煮る = boil/simmer vegetables, meat, etc.

You do not need:

• 野菜をや肉を... ← incorrect

The single を applies to the whole list.

In this sentence, よく means well or thoroughly, not often.

So:

• よく煮てから = after simmering/boiling well
• in natural English: after cooking it thoroughly

This is a very common point, because よく can mean two different things depending on context:

• よく行く = go often
• よく見る = look carefully / see well
• よく煮る = cook thoroughly

Here, because it is modifying a cooking action, thoroughly is the right sense.

煮て is the て-form of 煮る.

The て-form is used here because it connects to から in the pattern:

• Vてから = after doing V

So:

• 煮てから = after simmering/boiling

For this verb:

• dictionary form: 煮る
• て-form: 煮て

This is an ichidan verb, so it changes in a simple way:

• remove る
• add て

〜てから means after doing ... and usually shows that one action happens first, and then the next action happens.

In this sentence:

• よく煮てから、最後にみそを混ぜる
• After simmering it well, finally she mixes in the miso

It emphasizes sequence:

1. simmer the ingredients well
2. then add/mix the miso

This is especially common in instructions and recipes.

Not in exactly the same way.

• Vてから directly connects two actions in order: after doing V
• あとで is more like later or afterward

Examples:

• よく煮てから、みそを混ぜる = After simmering well, mix in the miso
• よく煮る。あとで、みそを混ぜる = Simmer well. Later, mix in the miso

So てから is the better choice when describing a clear step-by-step process.

最後に means finally or at the end.

The particle に marks the time/stage at which something happens.

So:

• 最後に = at the end / finally

This is very common in instructions:

• 最初に = first
• 次に = next
• 最後に = finally

It helps organize the steps of the recipe.

Because みそ is the direct object of 混ぜる.

• みそを混ぜる = mix the miso

In more natural English for cooking, this often becomes:

• mix in the miso

Japanese uses を because miso is the thing being mixed.

Literally, 混ぜる means to mix.

But in cooking English, this sentence is often translated more naturally as:

• mix in the miso
• add the miso and stir it in

So the literal sense is mix, but the practical recipe meaning is add and mix in.

No, it is already stated.

The structure is:

• 野菜や肉をよく煮てから = after simmering the vegetables, meat, etc. well
• 最後にみそを混ぜる = finally mix in the miso

The first verb, 煮て, takes 野菜や肉 as its object. The second verb, 混ぜる, takes みそ as its object.

So each verb has its own object.

Because Japanese often omits things that are already clear from context.

Here, 母は at the beginning sets the topic, and it naturally continues to apply to both actions:

• mother simmers the ingredients
• mother mixes in the miso

Repeating the subject would be unnecessary unless the speaker wanted special emphasis or a contrast.

Yes. Adverbs like よく usually go before the verb they modify.

So:

• よく煮る = cook/simmer well
• 野菜や肉をよく煮てから = after simmering the vegetables and meat thoroughly

Placing よく there clearly shows it modifies 煮て rather than the whole sentence.

A useful breakdown is:

• 母は = as for my mother
• 鍋で = in a pot
• 野菜や肉を = vegetables, meat, etc.
• よく煮てから = after simmering them well
• 最後に = finally
• みそを混ぜる = mixes in the miso

So the basic pattern is:

Topic + place/method + object + first action + after that + final step

This kind of structure is very common in recipe-style Japanese.
