No matter who cooks it, the food always has the same taste and texture.
Whichever person cooks it, they always make food with the same flavour and texture.
日本語の文に近いの英文にしたら:
Whichever person cooks it, they always make food with the same flavour and texture.
どんな人が料理しても、いつも同じ味と食感の食事を作る。
食感 = (food) texture
味 = flavour / taste
このように言うのは英語でもっと自然だと思います:
No matter who cooks it, the food always has the same taste and texture.
誰が作っても、食事はいつも同じ味と食感です。
