How can you limit what you display MYSQL

Hi,
So I am trying to display some items from the database, based on user preferences (aka keywords)

What I'm trying to do is only display e.g 3 recipes at a time. I tried to do an SQL count to count the rows, but doesnt seem to work, only row count i can get is for one item, for example, one item has row count of 3. But i need them for all items.
I tried LIMIT sql as well and didnt work

Is there an easier way to do this than the below? using a while loop which loops through all keywords and displays, however I need something else- i need to display 3 items, and then later on....if something happens, display 1 more??

What I have tried:

    if ($$meal == '1') //whether the user selected the keyword. (1=True)
        {
        $dbQuery = $conn->prepare("select * from Meal where Category='meal' AND Keyword = '" . ($$Keyword) . "'"); //get all recipes where keyword = word user selected
        $dbQuery->execute();
	

    while ($dbRow=$dbQuery->fetch(PDO::FETCH_ASSOC)) 
        {
            echo "//all infromation on this";
		}
				echo $dbQuery->rowCount()."\n";
    } 
}
