Late, but thank you for the rec! I recall being relatively busy when I first saw this comment, but read the novel today and wow, tasty crime solving? Hell yeah. I read the entire TL and then everything available on the MTL, and was surprised that it actually managed to combine the themes of a food/restaurant novel and a crime novel quite well, keeping both the food tasty and the plot engaging. Going to add it to my list and add a blurb later. 

Strange World Little cooking Saint:

Finished TL, may MTL. It's hard to rate because the translator seems to have changed a lot of the original work, to the point where it seems better to rate them separately. Can't recommend the TL as a cooking novel, because while I appreciate the TL's dedication to fixing things, it doesn't feel as mentally tasty to read when you know that there's 999 cooking errors and snarky TL fix-it notes everywhere. It's fun, but it breaks mental appetite and suspension of disbelief. The food often also isn't described all that well, which is probably an issue inherent to the novel, seeing as there are apparently so many blatant errors. 

Accidentally born in the '60s:

MTL. Not focused on cooking/food per se, but there's a solid amount of food present, as is to be expected when the first arc is focused on solving the family's poverty. Presence of food intermittently throughout afterwards, primarily focused on catching/obtaining it and eating heartily, and not so much the cooking itself. The MTL is readable, and the TL right now seems to be a very rough MTL anyway, seeing as "grandma" has been directly translated to "milk" in the TL. (The character is the same 奶.)

 The King of Hell's Genius Pampered Wife:

Maybe I just haven't read enough of it, but idk why tf this is tagged with cooking when cooking (and food) doesn't seem that important at all. 

 The Grand Secretary's Genius Pampered Wife:

I can see why it's tagged cooking, and food does show up often, but it's not a foodie novel. Despite the bucketload of tropes it starts with, I liked the novel quite a bit, but the military stuff is more memorable to me than the food, sooo...

 After I Livestreamed Raising Cubs I Became The Wealthiest In Interstellar:

The food is present, but it's often hard to really relate to because a lot of it is magical sci-fi future energy beastman food. It's fine if it's not real food, but the descriptions are less about the taste and more about the cool sci-fi effects the food has, in a way that's kind of overly cutesy. The novel itself...it's funny now and then, but tries way, way, way too hard to sell meng all the time. Exhausting. Saccharine. 

 Transmigrated to the '80s to be a Stepmother:

Decently tasty. I MTL' d and don't remember how it ends, but the food was pretty good. 

Isekai Izakaya Nobu:

This sucks. Dropped at CH17. Everything about the novel is too s*upid. This wouldn't necessarily matter for food p*rn if it just has a shitty plot, but the problem is that it's s*upid in a way that affects the food p*rn and makes me feel like "this author doesn't know jacksh*t about food". The English TL is also awkward to read, which decreases mental tastiness; I don't know if the original handles that better. 

Shuangwen Female Main Character Doesn’t Want To Be a Sensation:

Decently tasty but not food focused. It's an entertaining light read, but peters out towards the end. It's not a food novel, though.

There Will Always Be Protagonists With Delusions of Starting a Harem:

The food was okay, I guess? I don't remember it showing up enough for it to deserve the cooking tag. Otherwise, I like the concept, but the pacing is complete garbage; disappointing in execution. It's not very good overall.

Traveling Through Ancient Times To Be a Shopkeeper:

Reasonably tasty. Might put it on the list, but I dunno. The thing about this novel is that even though the businesses the MC opens are generally food/food-related businesses, the novel itself is way more focused on the business aspect than the 'tasty food' aspect.

I Became a Witch in a World Full of Urban Legends:

why is this even tagged cooking.

okay, no, I kind of understand why, but most of this novel is absolutely not tasty. (so far, anyway.) anyway, it's not cooking in the tasty way. it's cooking in the 'I'm chopping horror monsters into salad" way.

Isekai Nonbiri Nouka:

Didn't get very far in. It's not tasty because it reads like I'm going over a script for a toddler and has basically 0 descriptive language. It feels like it's just not written for a prose format, which is bad, because as a light novel, it's primarily prose. I think it'd be acceptable if this was the script for a manga, but...it's supposed to be prose. While I'm not a fan because I think it's written really badly, I also don't think it's tasty because there's no mental tastiness if the novel just skips descriptions and goes, "I ate a roasted rabbit. I went to sleep." 

Top Assassin Retires and Becomes a Farmer After Time Traveling to the Past:

The food is actually pretty good and shows up reasonably often, but I don't think I'd consider it a foodie novel. The problem is kind of similar to "The Grand Secretary's Genius Pampered Wife" -- sure, there's food and it's tasty, but overall, the more memorable part of this novel is how it Steampunks Ancient China.

Rebirth to the Eighties to Get Rich:

It's fine. It's somewhat tasty when food shows up, but it's not food-focused. In-between, there's tons of excessive filler and the plot is grating and draggy. Not worth reading as a food novel. 

Transmigrated into a Stepmother of Male Lead and Teaching My Lazy Son how to Study:

Fun slice-of-life read, but not a food novel. The food has magical effects, but is often comically terrible. 

After Reincarnating into Ancient Times, She Bound a Express Delivery System:

Extremely unserious and chill. Ok slice-of-life transmigration junk food read. Not a foodie novel. There are food businesses and food is mentioned decently often, particularly in the first portion, and the food is tasty, but it isn't described with too much detail or care.
