Leviticus 1 starts out with the Lord commanding how Aaron and his sons are to sacrifice livestock. It's interesting in that the Lord commanded a free will offering of a male that came from the herd. I'm not too sure what livestock were part of a herd, maybe cattle. Verse 10 talks about how if the offering is from a flock, which are sheep or goats, then it also needs to be a male without blemish! Maybe it symbolizes Jesus, who was without sin, dying on the cross willfully for our sins in a way because he is known to be the sacrificial lamb for the sins of believers.
It's interesting that in verse 9, it talks about an offering made by fire that is a sweet aroma to the Lord. Verse 14 seems to feel like it got creative in that the Lord even allowed for birds to be sacrificed! However, they had to be turtledoves or young pigeons. Verse 17 describes how after draining all the blood, removing the feathers, splitting it at its wings and then offering it as burnt sacrifice, it creates a sweet aroma to the Lord.

Leviticus 2 starts out with how anyone could do a grain offering to the Lord. It had to be fine flour and poured with oil and have frankincense on it. I think that might smell really good to the human nose while burned by fire! Verse 2 states that it's also a sweet aroma to the Lord while it's used as a memorial on the altar.
Right now, I feel like how all these rules and regulations could get a little too tied down for me. Back then, it might be cool to do it a few times, but having to do it often might just turn really boring. It probably has to deal with fearing and trusting the Lord enough to want to honor Him under all circumstances.
Verse 3 states that after a portion of the grain offering is burned, then the rest goes to Aaron and his sons, so I guess future generation of priests would get their food this way. Verse 10 notes that a grain offering is the most holy to the Lord made by fire. I am conjecturing that I wouldn't have to bring in the meat so often and keep my livestock alive while just passing off some left over fine flour to give rather frequently. Life might have not been so bad after all for meat lovers!
Verse 13 states that it is required for the grain offering to be seasoned with salt, which represents a covenant with God. I'm not sure what green heads of grain roasted on the fire, grain beaten from full heads really means which is depicted in Verse 14.

Leviticus 3 starts out with how a sacrificial peace offering from a Lord can be either male or female without any blemish! I guess this could account for being that God doesn't really discriminate based on gender. The New Testament talks about how there really isn't a male or female in heaven and that both genders were meant to be children of God and partake of God's blessings equally.
What seems to be an important commandment is that the killing of the offering was to be done outside the tabernacle (a huge tent constructed in Exodus for God's dwelling place) of meeting. Throughout this chapter, I'm sure fatty tissue can be rather tasty in a way but just imagining drinking it down gives a sick feeling to my stomach. The Lord commands it to be thoroughly removed of all the fat and offered to Lord. There was later in the Bible this was one priest who hogged all the fat and didn't really respect this common tradition laid out by God. What happened to him is that he led the people astray and probably went along with that feeling of wanting to not really care about living for the things of God, which was also on the minds of God's people. The Lord seriously took out like a rod or something and spanked them really good by causing some really hard times for the people.
Verse 17 states that restraining from eating fat and blood were to be done from here on out. That's a part of doing what's meant to be Kosher then I guess.
