your aunt or uncle
It’s most likely your aunt who would know that you ate onions before dinner, especially if she is more involved in meal preparation or has a closer relationship with you regarding your eating habits. Aunts often take on a nurturing role and might notice such details. Your uncle may not pay as much attention to these specifics.
Your Aunt would definitely be the one to know. As the woman in that family, your Aunt is less likely to leave the kitchen, hence the reason she would recognize the smell of onions better than your Uncle. =]
