考え直してみると...

Question 1

これを本当の LaTeX プロジェクトにしてくれた @alephzero に感謝します。つまり、LaTeX マークアップではなくレシピのセマンティクスに集中してくれたということです。

そのため、私はすっきりと整理された入力と出力を好みます。私は、\obeylines付随するマークアップなしでリスト環境をエミュレートするために使用しました。また、いくつかの可能性を示すために少し色を使用しました。私は、非常に単純なコードに、道を示すコメントを含めました。Computer Modern は私の選択ではありませんが、あなたの TeXing 環境が何であるかを知りませんので、不都合な仮定をしたくありませんでした。レシピのプレゼンテーションをできるだけ明確にするために、装飾 (ルールなど) を最小限に抑えます。どうぞお楽しみください。

後で：

不足しているをいくつか追加しました%。さらに、のオプション引数としてヘッドノートの可能性を追加しました\recipe。さらに、私自身の便宜を図るため、を利用してgeometry.sty5.5 インチ x 8.5 インチの出力を作成しました。もちろん、これは必要に応じて変更できます。

さらに後ほど:

また、これはとからTOC を使用して作成されることも指摘しておく必要があります\frontmatter。ピーナッツのようなもので、1 個だけ食べることはできません...\backmatterbook.cls

考え直してみると...

私はこの形式があまり好きではないのですが、二分法、材料が視覚的にはっきりとした場所に表示され、作り方とはまったく別物になっています。表面上、この目的は、ユーザーが最初に必要な原材料が何であるかを確認できるようにすることです。イザベラ・ビートン（家政書、1861年、彼女は読者に「レシピに書かれている順番に正確に従うこと。つまり、まず必要な材料をテーブルに並べること。そうすれば、調理法、つまり調理方法は簡単に管理できる」と勧めた。これは現在では一般的に「調理法」と呼ばれている。ミス・アン・プレイス。 しかし、特に長いレシピでは、目が材料と調理法の間を行ったり来たりしているうちに、何か（多くの場合は材料）が失われたり読み間違えられたり、手順が飛ばされたり誤解されたりすることが多すぎます。この影響は、長すぎるテキスト行を読むのと似ています。目は次の行の始まりを正確に見つけることができず、同じ行をもう一度読んだり、行を飛ばしたりします。（https://www.fonts.com/content/learning/fontology/level-2/text-typography/length-column-width) いずれにせよ、私はこのレシピをかなり異なる形式でフォーマットするだろうとだけ言っておきます (下記参照)。

今のところ、このレシピをそのまま使って、別の問題、つまり材料の指定について触れることにします。印刷物で二部形式が登場して以来（英語では19世紀初頭）、材料は明確に区別された方法で記載されてきました。物語形式：塩小さじ1杯、小麦粉1カップ、ココア2オンスなど。会話では慣用句ですが、印刷物では、額成分が話題になっているのではなく、身元材料そのもののことです。幸いなことに、TeX は、この慣習的な (満足のいくものではないが) 形式を不必要なマークアップで過度に乱すことなく、材料を解析することでこれを修正するツールを提供しています。さらに、材料は、数量が先行しない場合にのみ大文字にする必要があります (Whitman、レシピをタイプ別に分類、pp.124--125) も参照のこと。さらに、計測単位は省略しないのがベストである (Whitman,レシピをタイプ別に分類、スペースが限られている場合を除き、本文は pp. 15--16 にのみ引用します。

さらに、OpenType フォント (STIX Two) で度記号 (°) と分数 (½) を処理することで、コーディングをさらに最小限に抑えています。

\recipe[Some would say this is better than pie. It is certainly easier. And delicious. The original recipe came from Dorie Greenspan; this version also includes almond flour, suggested by King Arthur Baking.]{French Apple Cake}[Center a rack in the oven and preheat the oven to 350°F. Generously butter an 8-inch springform pan and put it on a baking sheet lined with a silicone baking mat or parchment paper.]
\serves{6-8}
\preptime{1 hour}
\cooktime{1 hour}
\dishtype{\dessert}
\dishother{\glutenfree}

\begin{step}
. . Batter, the dry:
1 cup AP (or GF) flour
½ cup almond flour
1 teaspoon baking powder
½ teaspoon cinnamon
¼ teaspoon nutmeg
¼ teaspoon salt
\method
Whisk the flour, baking powder, spices, and salt together in small bowl.
\end{step}

\begin{step}
4 large apples (if you can, choose 4 different kinds)
\method
Peel the apples, cut them in half and remove the cores. Cut the apples into 1- to 2-inch chunks.
\end{step}

\begin{step}
. . Batter, the wet:
2 large eggs
¾ cup maple or brown sugar
3 tablespoons dark rum
½ teaspoon pure vanilla extract
2--3 drops lemon extract
8 tablespoons unsalted butter, melted and cooled
\method
In a medium bowl, beat the eggs with a whisk until they’re foamy. Pour in the sugar and whisk for a minute or so to blend. Whisk in the rum, vanilla, and lemon oil. Whisk in  the flour and when it is incorporated, add the melted butter, mixing gently so that you have a smooth, rather thick batter.

Use a rubber spatula to fold-in the apples--it might look as if there isn't enough batter, but there is. Put the batter into the prepared pan, smoothing the top as much as possible. Bake for 55--65 minutes, or until a toothpick inserted  in the middle comes out clean.

Let cool 30 minutes. Before removing the side of the springform pan, run a knife around the edge of the cake to make sure no apples stuck to the pan.
\end{step}

Answer

これを本当の LaTeX プロジェクトにしてくれた @alephzero に感謝します。つまり、LaTeX マークアップではなくレシピのセマンティクスに集中してくれたということです。

そのため、私はすっきりと整理された入力と出力を好みます。私は、\obeylines付随するマークアップなしでリスト環境をエミュレートするために使用しました。また、いくつかの可能性を示すために少し色を使用しました。私は、非常に単純なコードに、道を示すコメントを含めました。Computer Modern は私の選択ではありませんが、あなたの TeXing 環境が何であるかを知りませんので、不都合な仮定をしたくありませんでした。レシピのプレゼンテーションをできるだけ明確にするために、装飾 (ルールなど) を最小限に抑えます。どうぞお楽しみください。

後で：

不足しているをいくつか追加しました%。さらに、のオプション引数としてヘッドノートの可能性を追加しました\recipe。さらに、私自身の便宜を図るため、を利用してgeometry.sty5.5 インチ x 8.5 インチの出力を作成しました。もちろん、これは必要に応じて変更できます。

さらに後ほど:

また、これはとからTOC を使用して作成されることも指摘しておく必要があります\frontmatter。ピーナッツのようなもので、1 個だけ食べることはできません...\backmatterbook.cls

考え直してみると...

私はこの形式があまり好きではないのですが、二分法、材料が視覚的にはっきりとした場所に表示され、作り方とはまったく別物になっています。表面上、この目的は、ユーザーが最初に必要な原材料が何であるかを確認できるようにすることです。イザベラ・ビートン（家政書、1861年、彼女は読者に「レシピに書かれている順番に正確に従うこと。つまり、まず必要な材料をテーブルに並べること。そうすれば、調理法、つまり調理方法は簡単に管理できる」と勧めた。これは現在では一般的に「調理法」と呼ばれている。ミス・アン・プレイス。 しかし、特に長いレシピでは、目が材料と調理法の間を行ったり来たりしているうちに、何か（多くの場合は材料）が失われたり読み間違えられたり、手順が飛ばされたり誤解されたりすることが多すぎます。この影響は、長すぎるテキスト行を読むのと似ています。目は次の行の始まりを正確に見つけることができず、同じ行をもう一度読んだり、行を飛ばしたりします。（https://www.fonts.com/content/learning/fontology/level-2/text-typography/length-column-width) いずれにせよ、私はこのレシピをかなり異なる形式でフォーマットするだろうとだけ言っておきます (下記参照)。

今のところ、このレシピをそのまま使って、別の問題、つまり材料の指定について触れることにします。印刷物で二部形式が登場して以来（英語では19世紀初頭）、材料は明確に区別された方法で記載されてきました。物語形式：塩小さじ1杯、小麦粉1カップ、ココア2オンスなど。会話では慣用句ですが、印刷物では、額成分が話題になっているのではなく、身元材料そのもののことです。幸いなことに、TeX は、この慣習的な (満足のいくものではないが) 形式を不必要なマークアップで過度に乱すことなく、材料を解析することでこれを修正するツールを提供しています。さらに、材料は、数量が先行しない場合にのみ大文字にする必要があります (Whitman、レシピをタイプ別に分類、pp.124--125) も参照のこと。さらに、計測単位は省略しないのがベストである (Whitman,レシピをタイプ別に分類、スペースが限られている場合を除き、本文は pp. 15--16 にのみ引用します。

さらに、OpenType フォント (STIX Two) で度記号 (°) と分数 (½) を処理することで、コーディングをさらに最小限に抑えています。

\begin{method}[Preheat the oven to Gas Mark 4, Electric \temp{180}, Fan \temp{160}.]
     Stir the two kinds of flour together in a bowl, add the butter and rub it into the flour. When the mixture looks like breadcrumbs, mix in the brown sugar. Lay the mixture on a shallow baking tray and bake for 25--30 minutes until golden brown. Leave on the side to cool.

     Mix together the mascarpone, sweetener, vanilla extract, and three quarters of the chocolate. Put half the crumble mixture in each of the glasses and pour over half the quark mixture along with half the raspberries.

     Put the other half of the crumble mixture on top, followed by the remaining quark mixture and raspberries. Sprinkle over the last of the chocolate. Chill for 3 hours before serving.

\recipe[Some would say this is better than pie. It is certainly easier. And delicious. The original recipe came from Dorie Greenspan; this version also includes almond flour, suggested by King Arthur Baking.]{French Apple Cake}[Center a rack in the oven and preheat the oven to 350°F. Generously butter an 8-inch springform pan and put it on a baking sheet lined with a silicone baking mat or parchment paper.]
\serves{6-8}
\preptime{1 hour}
\cooktime{1 hour}
\dishtype{\dessert}
\dishother{\glutenfree}

\begin{step}
. . Batter, the dry:
1 cup AP (or GF) flour
½ cup almond flour
1 teaspoon baking powder
½ teaspoon cinnamon
¼ teaspoon nutmeg
¼ teaspoon salt
\method
Whisk the flour, baking powder, spices, and salt together in small bowl.
\end{step}

\begin{step}
4 large apples (if you can, choose 4 different kinds)
\method
Peel the apples, cut them in half and remove the cores. Cut the apples into 1- to 2-inch chunks.
\end{step}

\begin{step}
. . Batter, the wet:
2 large eggs
¾ cup maple or brown sugar
3 tablespoons dark rum
½ teaspoon pure vanilla extract
2--3 drops lemon extract
8 tablespoons unsalted butter, melted and cooled
\method
In a medium bowl, beat the eggs with a whisk until they’re foamy. Pour in the sugar and whisk for a minute or so to blend. Whisk in the rum, vanilla, and lemon oil. Whisk in  the flour and when it is incorporated, add the melted butter, mixing gently so that you have a smooth, rather thick batter.

Use a rubber spatula to fold-in the apples--it might look as if there isn't enough batter, but there is. Put the batter into the prepared pan, smoothing the top as much as possible. Bake for 55--65 minutes, or until a toothpick inserted  in the middle comes out clean.

Let cool 30 minutes. Before removing the side of the springform pan, run a knife around the edge of the cake to make sure no apples stuck to the pan.
\end{step}

Question 2

これは完全ではありません (いずれにせよ、あなたが本をどのように見せたいのか正確にはわかりません!) が、実行でき、基本的なアイデアが伝わります。
