Shouldn't this still work? Need to echo out an unordered list IF $recommendations array isn't empty. 

<?php
$recommendations = array();

?><html>
<body>

    <h1>Flavor Recommendations</h1>

<?php
        if($recommendations !="") {
            echo '<ul>';
        foreach($recommendations as $flavor) { 
            echo '<li>' .  $flavor . '</li>'; }
            echo '</ul>';
        } 
?>

</body>
</html>
