Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

Q: CONTEXT: Use part of the shell you just cracked to scoop it up; it will attract the broken bit.Also, if you frequently end up with bits of shell in your eggs, you should revise your cracking technique. Eggs should be cracked on a flat surface (countertop or plate) not a sharper surface like the edge of a bowl.  <sep>  Q: I was wondering how to remove bits of egg shell from a cracked egg? A: Use part of the shell you just cracked to scoop it up; it will attract the broken bit  Q: Is there anyway I could do to prevent these egg shells from getting in the egg in the first place? A: if you frequently end up with bits of shell in your eggs, you should revise your cracking technique  <sep> FOLLOWUP_Q: Well how should I crack them then?

A: Eggs should be cracked on a flat surface (countertop or plate) not a sharper surface like the edge of a bowl.

Q: CONTEXT: In a cookbook that old, the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration. You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead. That product is similar, but made in much larger batches with a highly standardized, refined bacterial culture, producing a product with a predictable sourness and texture. Home-cultured versions are more variable, but they use similar processes on a much smaller scale.Whether you want to call this the "same" is partly a linguistic distinction that depends on how much you want to consider the differences in scale and equipment between pre-refrigeration and modern methods.In contrast, the addition of something sour to cream is really a substitute, used when you don't have a proper sour cream available. A cook back in the 1890s could use the same substitution then as we might today. But the production of sour cream (and all sorts of fermented milk products, such as yogurt and kefir) is much older than that, and there would have been some variety of "traditional" sour cream available, though not universally or year-round in the days before mechanized food distribution systems.  <sep>  Q: Is sour cream in olde recipes the same as sour cream today? A: the sour cream referenced is probably a home-fermented variety, used as a preservation method in the days before widespread home refrigeration  <sep> FOLLOWUP_Q: How would I make a home-fermented variety of sour cream?

A: You can still do this with the appropriate bacterial cultures, but most of us now buy our sour cream at the store instead

Q: CONTEXT: I assume you're making normal maki (nori side out) and not California rolls.Are you leaving a 1/2 inch or so of blank nori (no rice) on the outside edge (the edge that you roll last)? If you slightly wet the bare edge of the nori with a little water on your finger it should help it stick together.  <sep>  Q: How do I stop sushi rolls from opening up? A: leaving a 1/2 inch or so of blank nori (no rice) on the outside edge  Q: What is causing that to happen? A: I assume you're making normal maki (nori side out) and not California rolls  <sep> FOLLOWUP_Q: Do the ingredients make a difference?

A:
a little water on your finger it should help it stick together
