Duʿāʾ after eating sweet dish
I know that the following duʿāʾ اللھم إني أسئلك حلاوۃ الإیمان is narrated from the Prophet ﷺ. However, is there any narration that mentions that the Prophet ﷺ recited or recommended this duʿāʾ when eating a dessert or a sweet dish?
Is it Sunnah to recite بسم الله وعلی بركة الله before eating? What should you read before eating? Should you read بسم الله or بسم الله الرحمن الرحیم or بسم الله وعلی برکة الله or بسم الله وبرکة الله ? What did the Prophet صلی الله علیه وسلم read?
