Question:
Can a berachah made before or while in the process of making another food item of the same category cover the food being prepared drink? For example if someone is making a cup of coffee and recites a blessing over water before the coffee is made, should another blessing be recited?
Thank you
Answer:
The bracha on the water will cover the coffee, The rule is that if you had a specific food in mind, that it is included in your bracha.
As a side point though, when a person drinks water and doesn't really want the water and isn't thirdsy, but only drinking it to help swallow some medication etc. then we don't say a bracha on that water. Therefore if sdome one wants to say a shehakol because he has a seek regarding berachos, he should not use water for this purpose.
