Try this:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:key name="tempItem" match="recipeml/menu/recipe/ingredients/ing" use="item"/>

<xsl:template match="/">
<xsl:apply-templates select="recipeml/menu"/>
</xsl:template>

<xsl:template match="menu">
<html>
<head>
<title>Shopping List</title>
</head>

<body>
<table width="100%" border="1">
<xsl:apply-templates select="//ing"/>
</table>

</body>
</html>
</xsl:template>

<xsl:template match="//ing">
<xsl:if test="generate-id()= generate-id(key('tempItem',item)[1])">
<tr>
<td>
<xsl:value-of select="./item"/>
</td>
<td>
<xsl:value-of select="sum(key('tempItem',item)/amt/qty)"/>
</td>
</tr>
</xsl:if>
</xsl:template>
</xsl:stylesheet>

In your original XLST you have to modify for-each :
<xsl:for-each select="item[generate-id(..)= generate-id(key('tempItem',.)[1])]">

key('tempItem',.) returns you "ing", so you have to use "ing" in both
generate-id() calls.
Inside the predicate [] the context node is "item", so you have to use
".." to get to the "ing"
