My eating habits I guess are quite odd, I do the same thing with kitkats, eat all the chocolate off, pretty much any chocolate bar is eaten in that way. I completely understand the crusts thing, I get them out of the way first too, I don't like foods being too crunchy or dry, I was alot worst as a child but I still don't like it now.
My cereal has to be soggy, I will throw away any crispy fries, I don't like food that isn't aesthetically pleasing so if a banana has a brown spot I won't eat it, if a crisp(potato chip) has a burnt bit, or one of those gross greeny / undercooked bits that is discarded too. Squash has to be sickeningly sweet, I will only drink diet fizzy drinks because regular coats my teeth in a layer of sugar that makes me retch. I eat all the good bits first and leave the not good until last apart from one bit. To explain I'll use yesterday's dinner as an example, I had sweet and sour chicken with rice, the chicken was coated in batter, I love those little squidgy tasty balls (if you sniggered at this then dirty minds think alike
). I had 4 pieces on my plate so I ate 3, then ate the rice / vegetables before really savouring the last bit (after carefully picking off and eating any bits of rice that had become stuck to it).
Hot chocolate has to be made in a specific way or it doesn't taste right to me. I get options instant hot chocolate, I pour the satchet in, add about 1/4 cup full of milk, stir, add boiling water until the cup is half full and stir, add more milk, stir, add more water stir but leave a small gap so I can top up with milk. This ensures that the powder is completely dissolved and I don't get that disgusting gunk at the end of the cup and the large amount of milk makes it the right temperature. If I'm having marshmallows they have to be added before any water because then they will be slightly melted, nothing worst to me then a dry, slightly powdery marshmallow.
I have certain ways of preparing / eating virtually everything that passes my lips and I have set meal plans and eat the same food for weeks or months (not the exact same but for example I have 7 different meals that I have and I will buy those same foods for probably the next 2/3 months before I move on to something else). Up until recently I never thought it was strange, I assumed everybody did things this way or in similar ways (had their own little rituals). A major factor being that my husband is the same with eating things a certain way, certain foods and they have to be prepared a certain way, same with my daughter, so it never seemed like it might be unusual until I started reading bits and pieces on here.
