As shown in this answer, Owen and Beru Lars should be very familiar with C-3PO (he stayed with Shmi Skywalker till her death, and was present at her funeral).

Yet, Lars (not sure if Beru saw him during ANH) never recognizes C-3PO in the first part of A New Hope, despite presumably having lived with him during the time of Shmi Skywalker's marriage to Cliegg Lars. 

Is there a canon explanation for Owen's lack of recognition?

Question: Oatmeal & Lactose Intolerance
Answer: You can try some hydrocolloid thickeners like xanthan gum or guar gum. These generally are used in small amounts and dispersed in a cold liquid. These will help the oatmeal seem "creamier". (FWIW, Quaker Oatmeal's non-dairy flavored oatmeals include guar gum for this very reason.)
